Ingredients
Method
- Prep and preheat: Heat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or butter. Pat the shrimp dry and season with a pinch of salt, pepper, and half the smoked paprika.
- Sauté aromatics: Warm 2 tablespoons olive oil in a large skillet over medium heat. Add onion and bell pepper with a pinch of salt. Cook 5–6 minutes until soft. Stir in garlic and cook 30–60 seconds until fragrant.
- Wilt the greens: Add spinach to the skillet and cook until just wilted (about 1–2 minutes). If using frozen spinach, stir until heated through.
- Make the creamy base: Lower heat. Stir in broth, Greek yogurt, Dijon, remaining smoked paprika, red pepper flakes (if using), lemon zest, and half the lemon juice. Warm gently, then fold in Parmesan until it melts. Taste and season well with salt and pepper. The sauce should be savory and bright.
- Combine with rice: Add the cooked rice to the skillet. Fold to coat every grain. If it looks too thick, splash in a bit more broth to loosen; it should be creamy but scoopable.
- Add shrimp: Fold in the seasoned shrimp and most of the parsley. The shrimp will finish cooking in the oven, so don’t cook them on the stovetop.
- Assemble: Transfer the mixture to the prepared baking dish. Sprinkle mozzarella on top. For extra crunch, mix panko with a teaspoon of olive oil and a tablespoon of Parmesan, then scatter over the cheese.
- Bake: Bake uncovered for 14–18 minutes, until the shrimp are opaque and just cooked through and the top is lightly golden. Avoid overbaking to keep the shrimp tender.
- Finish: Squeeze the remaining lemon juice over the casserole. Let it rest 5 minutes so it sets slightly. Top with extra parsley and a little more Parmesan if you like.
- Serve: Scoop into bowls and enjoy hot. Add a side salad or steamed broccoli for more veggies.

Storage Instructions
- Fridge: Cool completely, then store in an airtight container for up to 3 days.
- Reheating: Warm individual portions in the microwave in 60–90 second bursts, stirring once. Or reheat covered in a 325°F (165°C) oven until hot.
Add a splash of broth if it seems dry.
- Freezer: Freeze in airtight containers for up to 2 months. Thaw overnight in the fridge, then reheat gently. Note: the texture of shrimp can firm up slightly after freezing, but it’s still tasty.
Why This is Good for You
- Lean protein: Shrimp offers high-quality protein with minimal fat, which supports muscle repair and keeps you full.
- Probiotics and calcium: Greek yogurt adds creaminess without heavy cream and brings extra protein and nutrients.
- Whole grains (if you choose brown rice): More fiber for steady energy and better satiety.
- Micronutrients: Spinach, peppers, lemon, and parsley add vitamins A, C, K, and antioxidants.
- Balanced macros: Carbs from rice, protein from shrimp/yogurt/cheese, and healthy fats from olive oil create a satisfying, well-rounded meal.
Common Mistakes to Avoid
- Overcooking the shrimp: Bake just until opaque.
Overbaked shrimp turn rubbery fast.
- Watery spinach: If using frozen spinach, squeeze it very dry. Excess water will thin the sauce.
- Skipping seasoning: Taste the sauce before baking. It should be well salted and bright from lemon.
- Using hot yogurt: Don’t boil the yogurt sauce.
Gentle heat prevents curdling and keeps it smooth.
- Too-dry rice: If your rice is very dry, add an extra splash of broth before baking to keep the casserole creamy.
Alternatives
- Protein swaps: Use cooked chicken breast or firm tofu cubes instead of shrimp. For fish, flake in cooked salmon right before baking.
- Dairy-free: Replace Greek yogurt with a thick, unsweetened coconut yogurt and use a dairy-free mozzarella-style shreddable. Season generously to balance flavors.
- Low-carb: Swap rice with cooked cauliflower rice.
Reduce broth slightly so it doesn’t get watery.
- Veggie boost: Add peas, sautéed mushrooms, or roasted zucchini. Keep total volume similar so the casserole sets well.
- Spice profile: Trade smoked paprika for Cajun seasoning or Old Bay. Adjust salt if your blend contains it.
- Cheese twist: Try Gruyère or sharp cheddar for a deeper, nuttier top.
FAQ
Can I use precooked shrimp?
Yes.
Fold in thawed, well-drained precooked shrimp in step 6 and reduce bake time to about 10–12 minutes, just to heat through and melt the cheese.
What rice works best?
Day-old jasmine or brown rice holds texture well. Freshly cooked rice can be used, but spread it on a tray to steam off excess moisture before mixing.
Is there a way to make it spicier?
Add more red pepper flakes, a diced jalapeño with the onions, or use a Cajun seasoning blend. Taste as you go so the heat doesn’t overpower the lemon and shrimp.
Can I make this ahead?
Assemble up to the point of baking, cover, and refrigerate up to 24 hours.
Add 5–8 extra minutes to the bake time if going into the oven cold.
How do I prevent the yogurt from curdling?
Keep the heat low when adding yogurt, and don’t let it boil. Stir in gradually and warm gently until smooth.
What size shrimp should I buy?
Medium to large shrimp (31–40 or 21–25 per pound) are ideal. They stay juicy and don’t overcook as quickly as smaller shrimp.
Can I use quinoa instead of rice?
Yes.
Use 3 cups cooked quinoa. It brings a slightly nutty flavor and adds even more protein and fiber.
How do I make it gluten-free?
Use gluten-free panko or skip the breadcrumbs. All other ingredients are typically gluten-free, but always check labels on broth and mustard.
In Conclusion
This High Protein Shrimp & Rice Casserole is comfort food without the slump.
It’s creamy, bright, and full of satisfying protein, with an easy method you can count on. Keep it simple on a busy weeknight, or dress it up with herbs and a crispy topping for guests. Either way, you’ll have a reliable, wholesome dish that tastes like more effort than it takes.
