This 21 Day Fix pork loin recipe transforms lean meat into a flavorful centerpiece for meal prep. Growing up in Georgia, I learned that simple seasonings and proper technique make all the difference with pork.
The secret is a dry rub of basic spices and a precise roasting method that keeps the meat juicy. I developed this approach while working at The Smoky Pig, where we served thousands of pork dishes weekly.
You’ll end up with tender, lean pork that fits perfectly into the 21 Day Fix container system. Each serving delivers maximum flavor without excess fat or calories.
Perfect for batch cooking and easy to customize with different herbs or spices. Here’s how to make it.
Ingredients for 21 day fix pork loin
Lean pork loin plus a handful of pantry spices. Simple, clean, and packed with flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin 🥩 | 2 lb | Boneless, trimmed of fat |
| Olive Oil 🫒 | 2 tbsp | Divided for rubbing and searing |
| Garlic Powder 🧄 | 1 ½ tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 ½ tsp | Adds depth to dry rub |
| Dried Thyme 🌿 | 1 tsp | Crushed between fingers |
| Dried Rosemary 🍃 | 1 tsp | Crushed between fingers |
| Paprika 🌶️ | 1 tsp | Sweet or smoked variety |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | 1 tsp | Freshly ground preferred |
| Dijon Mustard 🟡 | 1 tbsp | For tenderizing and flavor |
| Low-Sodium Chicken Broth 🥣 | ½ cup | For basting during roasting |
| Fresh Garlic Cloves 🧄 | 3 cloves | Minced for additional flavor |
The pork loin should be a uniform thickness—ask the butcher at Whole Foods or Publix to trim and tie it if you're unsure. Look for a cut with a nice fat cap you can leave on for flavor (or remove for strict 21 Day Fix). I always grab mine from Costco for batch cooking. The spices? Penzeys has the freshest, but your grocery store's bulk section works too.
Out of garlic powder? Use double the fresh minced garlic—just press it into the meat so it doesn’t burn. No Dijon? Whole-grain mustard works fine, though it’s slightly sweeter. Swap the herbs for whatever you’ve got—sage or oregano would be great. Skip the chicken broth if needed, but basting really does keep it juicy.
Roast and slice, then store in the fridge for up to 4 days. Freezes beautifully for 3 months. Portion into containers for grab-and-go meals—this is meal prep gold (the Georgia way, of course).

Step-by-step instructions for 21 Day Fix pork loin
Simple steps, big flavor—this lean protein comes out tender and perfectly seasoned every time.
Create the Dry Rub and Prep the Pork Loin
In a small bowl, combine the 1.5 tsp kosher salt, 1.5 tsp garlic powder, 1.5 tsp onion powder, 1 tsp dried thyme, 1 tsp dried rosemary, 1 tsp paprika, and 1 tsp black pepper. I crush the dried herbs between my fingers to release their oils for maximum flavor impact.
Pat the 2 lb pork loin dry with paper towels—this ensures the rub adheres properly and promotes even browning. Then rub the dry spice blend all over the surface, pressing it in so it forms a visible crust. The pork should look evenly coated with no bare spots.
Sear for Deep Flavor Development
Heat 1 tbsp olive oil in a large oven-safe skillet over medium-high heat until it shimmers. Add the pork loin and sear for 2-3 minutes per side until a deep golden crust forms. You’ll hear a satisfying sizzle when it hits the pan, and it should release easily when ready to flip.
Don’t rush this step—searing creates the Maillard reaction that gives the pork loin its rich, savory depth. Use tongs to turn it, and resist the urge to move it around too much. A good sear means less flipping, not more.
Add Aromatics and Begin Roasting
Reduce the heat to medium and add the minced 3 cloves fresh garlic cloves to the skillet. Stir for 30 seconds until fragrant, then add the remaining 1 tbsp olive oil, 1 tbsp Dijon mustard, and 0.5 cup low-sodium chicken broth. The mustard adds tang and helps tenderize the meat.
Baste the pork loin with the liquid in the pan, then transfer the skillet to a preheated 375°F oven. This initial basting step locks in moisture and infuses the pork with those bold aromatics. Make sure your oven is fully preheated for even cooking.
Roast to Perfect Doneness
Roast the pork loin for 30-40 minutes, basting with the pan juices every 10-12 minutes. The internal temperature should reach 145°F when measured in the thickest part. The juices should run clear, not pink, when you pierce it with a knife.
If the pan juices start to reduce too much, add a splash of water to prevent burning. The pork loin is lean, so those basting liquids are crucial for keeping it moist. You’ll know it’s close when the outside is golden and the inside feels slightly springy to the touch.
Rest and Slice for Serving
Transfer the pork loin to a cutting board and tent loosely with foil. Let it rest for 10 minutes—this step is non-negotiable. Resting allows the juices to redistribute, so every slice stays succulent instead of dry.
Slice the pork loin against the grain into ½-inch thick pieces. Each serving should be tender, juicy, and packed with the bold flavors from the rub and pan juices. Serve immediately with your favorite 21 Day Fix sides.
Pro Tips For Making 21 Day Fix Pork Loin
- Sear First, Roast After: Start with a hot pan and 2 tablespoons of olive oil to sear the pork loin on all sides—this locks in juices and gives it that golden crust I learned to prioritize after my first dry, bland attempt.
- Pat It Dry: Before seasoning, blot the pork loin with paper towels to remove excess moisture. Sounds tedious, but it makes the garlic powder and thyme stick better and helps the crust form properly.
- Don’t Overcook: Pull the pork loin at 145°F internal temp—it’ll rise to 150°F while resting. I ruined two loins by waiting for 160°F in the pan, and they turned out tough and dry.
- Rub It Right: Mix the garlic powder, onion powder, and dried thyme with a little olive oil to make a paste, then rub it all over the pork. This ensures even coverage and better flavor penetration than just sprinkling dry spices.

Frequently asked questions
How do I know when the pork loin is done?
Use a meat thermometer to check the internal temperature. It should read 145°F in the thickest part. The juices should run clear, not pink.
Can I use a pork tenderloin instead of loin?
Yes, but adjust the cooking time. Tenderloin cooks faster—roast for 20-25 minutes at 375°F instead. It’s leaner, so don’t overcook or it’ll dry out.
What if my pork loin is larger than 2 lbs?
Increase roasting time by 10-15 minutes per pound. Always use the thermometer as your guide. A 3 lb loin may take 45-50 minutes total.
How do I keep the pork from drying out?
Baste every 10-12 minutes with pan juices and don’t skip the 10-minute rest after cooking. These steps lock in moisture.
