How to Make High Protein Spaghetti Casserole Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 375°F (190°C) and lightly greasing a 9×13-inch baking dish. This prep work ensures your casserole bakes evenly and releases easily once cooked.
Step 2: Cook the Spaghetti
Boil the whole wheat or high-protein spaghetti until al dente according to the package directions. Drain it well to make sure the pasta doesn’t become soggy in the casserole, then set aside to cool slightly.
Step 3: Brown the Meat and Build the Sauce
In a large skillet over medium heat, cook your lean ground turkey or beef with the chopped onion until the meat is browned and fully cooked. Adding the garlic in the last minute infuses the mix with inviting aroma and flavor. Stir in the tomato sauce, Italian seasoning, salt, and black pepper, then let this simmer gently for five minutes to marry the flavors.
Step 4: Mix the Cheesy Layer
In a medium bowl, beat together the cottage cheese and plain Greek yogurt until smooth and creamy. This mixture will add moisture, tang, and a wonderful depth of flavor to your casserole layers.
Step 5: Assemble the Casserole
Layering is where the magic happens. In your prepared baking dish, start with half of the cooked spaghetti. Spread half of the hearty meat sauce over it, then dollop and spread half of the cheese mixture on top. Repeat the layers with the remaining pasta and sauce. This layering ensures each bite is perfectly balanced with noodles, savory meat, and creamy cheese.
Step 6: Add the Cheese Topping and Bake
Sprinkle shredded mozzarella and grated Parmesan evenly over the top. Cover the casserole with foil and bake for 20 minutes. Then, remove the foil and continue baking for another 10 minutes, or until the cheese is bubbling and golden. Let the casserole rest for 5 minutes before serving to let the flavors settle and the cheese firm up slightly.
How to Serve High Protein Spaghetti Casserole Recipe
Garnishes
A sprinkle of freshly chopped parsley adds a pop of color and fresh herbal brightness that complements the rich casserole perfectly. Feel free to add a drizzle of extra virgin olive oil or a pinch of crushed red pepper flakes for a little kick.
Side Dishes
This High Protein Spaghetti Casserole Recipe pairs beautifully with simple green salads dressed in lemon vinaigrette or roasted vegetables like asparagus or Brussels sprouts, which add texture contrast and a dose of vitamins.
Creative Ways to Present
For a fun twist, serve this casserole in individual ramekins for personalized portions that are perfect for dinner parties or meal prep. Adding a side of garlic bread or a crunchy topping made from toasted breadcrumbs and herbs also makes the presentation inviting and the meal even heartier.
Make Ahead and Storage
Storing Leftovers
Once completely cooled, transfer leftover casserole into an airtight container and store in the refrigerator. It keeps wonderfully for up to 4 days, making it perfect for quick lunches or easy dinners throughout the week.
Freezing
You can freeze this casserole for longer storage by wrapping it tightly with plastic wrap and then aluminum foil. Frozen portions will stay fresh for up to 3 months. Thaw overnight in the fridge before reheating for best results.
Reheating
Reheat individual portions in the microwave or warm up the entire casserole in a preheated oven at 350°F (175°C) covered with foil for about 20 minutes or until heated through. Adding a few spritzes of water before reheating can keep the casserole moist and delicious.
