Keto Garlic Butter Tilapia Meal Prep - Simple, Flavorful, and Ready for the Week

Prep Time 10 minutes
Cook Time 15 minutes
Total Time 25 minutes
Servings: 4 servings

Ingredients
  

  • Tilapia fillets: 4–6 fillets (about 1.5–2 pounds total), patted dry
  • Butter: 6–8 tablespoons, preferably grass-fed for richer flavor
  • Garlic: 4–5 cloves, minced
  • Lemon: Zest and juice of 1 lemon
  • Fresh parsley: 2–3 tablespoons, chopped (or use dill for a twist)
  • Paprika: 1 teaspoon (smoked or sweet)
  • Salt and pepper: To taste
  • Olive oil or avocado oil: 1 tablespoon for searing, if pan-cooking
  • Optional heat: A pinch of red pepper flakes
  • Lemon slices: For garnish and extra moisture
  • Low-carb sides: Broccoli, cauliflower rice, green beans, zucchini, or asparagus

Method
 

  1. Prep the tilapia: Pat fillets dry with paper towels. Season both sides with salt, pepper, and paprika. Add a light sprinkle of lemon zest if you like bright flavor throughout.
  2. Make the garlic butter: In a small saucepan, melt butter over low heat. Add minced garlic and cook 1–2 minutes until fragrant, not browned. Stir in lemon juice, remaining zest, chopped parsley, and a pinch of red pepper flakes. Set aside.
  3. Choose your cooking method: You can pan-sear for quick color or bake for hands-off ease. Both work great for meal prep.
  4. Pan-sear method: Heat a large skillet over medium-high. Add oil. Place fillets in the pan and cook 2–3 minutes per side, depending on thickness. Spoon some garlic butter over the fish as it finishes cooking.
  5. Bake method: Preheat oven to 400°F (200°C). Arrange fillets on a lined sheet pan. Brush generously with garlic butter and add lemon slices on top. Bake 8–12 minutes, or until the fish flakes easily with a fork.
  6. Cook your sides: While the fish cooks, roast or sauté your vegetables. Toss broccoli or green beans with oil, salt, and pepper, then roast at 400°F until crisp-tender. Or sauté zucchini ribbons in butter for 3–4 minutes.
  7. Finish and taste: Drizzle remaining garlic butter over the cooked fish. Adjust salt and lemon as needed. A final sprinkle of fresh herbs keeps it bright.
  8. Portion for meal prep: Divide tilapia and veggies into 4–6 airtight containers. Add a lemon wedge to each for reheating later.
