Recipe
Garlic butter pork tenderloin prepared in the Instant Pot delivers a perfect combination of tenderness and flavor, requiring minimal effort while producing restaurant-quality results. The pressure cooking method guarantees the meat stays juicy while developing a rich, savory taste from the garlic-infused butter sauce.
This keto-friendly dish transforms an ordinary pork tenderloin into an extraordinary meal, with the garlic butter sauce creating a luxurious finish that will impress both family and guests. The cooking process is straightforward, making it an ideal choice for busy weeknights when you want something special without spending hours in the kitchen.
- 1 pork tenderloin (1.5-2 pounds)
- 6 tablespoons butter
- 8 cloves garlic, minced
- 1 teaspoon salt
- 1 teaspoon black pepper
Season the pork tenderloin with salt and pepper, then set Instant Pot to sauté mode and melt butter. Add minced garlic and cook for 1 minute until fragrant. Place the pork in the pot and sear all sides until golden brown, approximately 2-3 minutes per side. Close lid, set valve to sealing position, and cook on high pressure for 5 minutes. Allow natural release for 10 minutes, followed by quick release of remaining pressure. Remove pork, let rest for 5 minutes, then slice and serve with the garlic butter sauce.
For best results, remove the pork tenderloin from the refrigerator 30 minutes before cooking to guarantee even cooking. Always use a meat thermometer to check that the internal temperature reaches 145°F (63°C) at the thickest part. If the sauce seems too thin after cooking, use the sauté function while the meat rests to reduce it to desired consistency. To prevent the garlic from burning during the initial sauté, keep it moving in the butter and watch it carefully.
Prep Time
The total prep time for this delicious pork tenderloin recipe is just 10 minutes, making it perfect for busy weeknights. You’ll need about 5 minutes to gather your ingredients and season the meat with salt and pepper. During this time, you can also mince your garlic cloves if you haven’t bought pre-minced garlic.
While you’re waiting for your pork to come to room temperature (30 minutes before cooking), you can prep other sides to go with your meal. I like to use this time to set up my Instant Pot and measure out my butter. Don’t worry if you’re in a hurry – you can skip the room temperature step, though you might need to add an extra minute to the cooking time.
Equipment needed
Success in making this tender pork dish relies on having the right tools ready to go. The star player is, of course, an Instant Pot – I recommend a 6-quart model, which perfectly fits a standard pork tenderloin. You’ll also need:
- Tongs for safely turning the meat while searing
- Meat thermometer to check internal temperature
- Sharp knife for slicing the cooked tenderloin
- Cutting board with juice groove
- Measuring spoons for precise seasoning
- Garlic press (optional, but makes mincing easier)
I’ve found that having all these tools lined up before starting makes the cooking process much smoother. Don’t worry if you don’t have a garlic press – a good chef’s knife works just fine for mincing. The most important thing is having that Instant Pot and meat thermometer ready to go.
Basic Cooking Method and Time
With your equipment ready, let’s get cooking! First, you’ll want to season your pork tenderloin with salt and pepper. Set your Instant Pot to sauté mode and melt the butter, then add your minced garlic and let it cook for about a minute until it’s nice and fragrant.
Next, place your seasoned pork in the pot and give it a good sear on all sides – about 2-3 minutes per side until it’s golden brown. Once that’s done, close the lid and set the valve to sealing. Cook on high pressure for 5 minutes, followed by a 10-minute natural release. After that, quick release any remaining pressure. Remember to let your pork rest for 5 minutes before slicing. Trust me, this resting time makes all the difference in keeping those juices locked in!
Cooking Steps
Following our basic cooking method, let’s break down these steps into manageable chunks so you’ll never feel overwhelmed.
First, you’ll want to season your pork tenderloin with salt and pepper, making sure to coat all sides evenly. Switch your Instant Pot to sauté mode and let that butter melt until it’s nice and bubbly. Now, drop in your minced garlic and give it a quick stir – you’ll know it’s ready when your kitchen smells amazing, about a minute in. Next, place your seasoned pork in the pot and sear each side until it’s golden brown. I usually give it about 2-3 minutes per side. Once it’s beautifully browned, close the lid, set the valve to sealing, and let your Instant Pot work its magic on high pressure.
Step 1. Bring Meat to Temperature
Before you start cooking that beautiful pork tenderloin, I’ve learned through countless trials that letting it rest at room temperature for 30 minutes makes a world of difference. Let me explain why this step is so essential: cold meat can lead to uneven cooking and tougher results. When you bring the meat to room temp, it’ll cook more evenly from edge to center.
While you’re waiting, it’s the perfect time to prep your other ingredients. I like to mince my garlic and measure out the butter and seasonings. Trust me, I’ve rushed this step before, and the results just weren’t the same. If you’re short on time, you can reduce the rest period to 15 minutes, but try to give it the full 30 if possible.
Step 2. Season Pork Generously
Let’s tackle seasoning your pork tenderloin, which I’ve found to be one of the most essential steps for amazing flavor. I always make sure to coat both sides of the meat generously with salt and black pepper, giving it an even distribution. You’ll want to really work the seasonings into the surface of the pork with your fingers.
Don’t be shy with the salt – I’ve learned through trial and error that pork tenderloin can handle more seasoning than you might think. The salt not only enhances the meat’s natural flavors but also helps create a delicious crust when you sear it. I recommend using about 1/2 teaspoon of salt and 1/2 teaspoon of pepper per pound of meat, adjusting to your taste preferences.
Step 3. Melt Butter in Pot
Once your pork is perfectly seasoned, it’s time to get that butter melting in your Instant Pot. Press the sauté button and wait for your display to read “HOT” before adding those 6 tablespoons of butter. You’ll want to watch it closely – butter can go from perfectly melted to burnt in no time!
I love this step because it fills my kitchen with that wonderful buttery aroma. Make sure you’re spreading the melted butter around evenly by giving your pot a gentle swirl. The butter should coat the bottom surface completely, creating the perfect foundation for searing your pork. Don’t rush this process – letting the butter melt gradually at the right temperature will help prevent it from separating or burning.
Step 4. Pressure Cook Pork
After you’ve seared that gorgeous pork to a golden brown, it’s time for the pressure cooking magic to happen. Close your Instant Pot lid securely and double-check that the valve is set to “sealing” position – I’ve forgotten this step before, and trust me, you don’t want that mistake!
Set your pot to high pressure for 5 minutes, then let it do its thing. Once the cooking time is up, you’ll want to let it naturally release pressure for 10 minutes – this is essential for keeping your meat tender. After that, go ahead and quick release any remaining pressure. The pork should reach an internal temperature of 145°F, which gives you that perfect balance of food safety and juiciness.
Step 5. Let Pork Rest Before Serving
Taking your perfectly cooked pork tenderloin out of the Instant Pot is just the beginning – now comes a step I learned the hard way during my early cooking days. Let me tell you, slicing into that beautiful piece of meat right away will cause all those flavorful juices to run right onto your cutting board instead of staying in the meat where they belong.
Give your pork tenderloin at least 5 minutes to rest under a loose foil tent. During this time, the meat’s internal temperature will continue rising slightly while the muscle fibers relax and reabsorb those precious juices. Trust me, this short wait is worth every second – you’ll end up with perfectly moist, tender slices instead of dry, tough meat. While you’re waiting, you can reduce that garlic butter sauce to perfection.
Customization Options
The beauty of this garlic butter pork tenderloin recipe lies in its incredible versatility. You can easily customize it to match your taste preferences or what’s available in your pantry. Try adding fresh herbs like rosemary, thyme, or sage to the butter sauce for an aromatic twist, or include a splash of white wine for extra depth.
For a spicier version, add red pepper flakes or cayenne to the seasoning mix. You can also experiment with different compound butters – think garlic-herb, lemon-parsley, or even truffle butter for special occasions. Don’t hesitate to toss in some mushrooms or shallots while sautéing the garlic – they’ll absorb all those delicious flavors and create an even richer sauce. Consider adding a touch of heavy cream at the end for a more indulgent finish.
Ingredients list (with precise measurements)
Every successful keto pork tenderloin recipe starts with precise measurements of quality ingredients. You’ll need a 1.5-2 pound pork tenderloin as your star ingredient, which is the perfect size for 4-6 servings. For the mouthwatering garlic butter sauce, gather 6 tablespoons of butter (I prefer unsalted to control the seasoning) and 8 cloves of minced garlic.
Let’s talk seasonings: you’ll need 1 teaspoon each of salt and black pepper – trust me, these simple seasonings are all you need to complement the rich garlic butter. I’ve found that using fresh garlic rather than pre-minced makes a noticeable difference in flavor. Keep these ingredients handy, and you’ll be ready to create this delicious keto-friendly meal that never fails to impress my dinner guests.
Storage Information
Since proper storage makes all the difference in keeping your pork tenderloin fresh and flavorful, I’ve learned some reliable methods through years of meal prepping. You’ll want to let your leftover pork cool completely before storing it in an airtight container. When properly stored in your refrigerator, it’ll stay fresh for up to 3 days.
For longer storage, you can freeze your garlic butter pork tenderloin for up to 3 months. I recommend slicing it before freezing and storing it with some of the sauce in freezer-safe containers or bags. When you’re ready to enjoy it again, thaw it overnight in the refrigerator and gently reheat it in the microwave or on the stovetop, adding a splash of broth if needed to keep it moist.
Health Benefits or Special Features
While following a keto diet can sometimes feel restrictive, this garlic butter pork tenderloin recipe offers an abundance of health benefits that’ll make you feel great about serving it. You’ll get plenty of high-quality protein from the pork, which helps maintain muscle mass and keeps you feeling satisfied. The butter provides healthy fats essential for ketosis, while garlic brings powerful antioxidants and immune-boosting compounds to your plate.
This dish is naturally gluten-free and fits perfectly into your low-carb lifestyle with zero added sugars. You’ll also love that it’s rich in B vitamins, particularly thiamin and B6, which support energy metabolism. Plus, using the Instant Pot means you’re preserving more nutrients compared to traditional cooking methods, making this recipe both delicious and nutritious.
Prep Time
One of the best features of this garlic butter pork tenderloin is its incredibly quick prep time. You’ll only need about 10 minutes to get everything ready before the cooking process begins. Simply season your pork, mince the garlic, and measure out your butter – that’s it!
To make your prep even more efficient, gather all your ingredients before starting. While you’re bringing the meat to room temperature (30 minutes before cooking), you can use that time to mince your garlic and get your measuring tools ready. I love that there’s no complicated marinade or fancy techniques required. If you’re really pressed for time, you can even mince the garlic in advance and store it in an airtight container in the fridge for up to 24 hours.
Cook Time
The total cook time for this keto pork tenderloin is remarkably quick at just 15-20 minutes from start to finish. You’ll spend about 6-8 minutes searing the meat on all sides in sauté mode, which helps lock in those amazing juices. Once you’ve got that beautiful golden-brown crust, it’s just 5 minutes at high pressure followed by a 10-minute natural release.
I love how the Instant Pot makes this process so efficient – you won’t believe the tender, juicy results you’ll get in such a short time. While the pork is cooking, you can prepare your sides or take a quick breather. Don’t forget to factor in that 5-minute rest period after cooking, which lets the meat’s juices redistribute perfectly throughout each slice.
Total Time
Since you’ll need about 35-40 minutes from kitchen to table, this keto pork tenderloin recipe fits perfectly into your weeknight dinner rotation. The time breaks down easily: you’ll spend about 10 minutes on prep and seasoning, 15 minutes searing and pressure cooking, 10 minutes for natural release, and 5 minutes for resting the meat before slicing.
I love that most of this cooking time is hands-off, giving you plenty of opportunity to prepare side dishes or help the kids with homework. While the pressure builds and releases, you’re free to toss a salad or steam some vegetables. Don’t skip the resting period, though – those final 5 minutes are essential for keeping your pork tenderloin juicy and tender.
Yield
Depending on the size of your pork tenderloin, you’ll get about 4-6 generous servings from this recipe. Each portion is perfect for a satisfying keto dinner, providing roughly 6-8 ounces of tender, butter-basted meat per person.
I love that the yield is so flexible – you can easily stretch it to feed more people by serving smaller portions alongside veggie sides, or keep the portions larger for hearty eaters. If you’re cooking for two, you’ll have fantastic leftovers for lunch the next day. When I make this for my family, I sometimes grab two tenderloins if we’re hosting guests or want extra for meal prep through the week. The garlic butter sauce goes a long way too, giving you plenty to drizzle over each slice.
