How to Make High Protein Spaghetti Casserole Recipe
Step 1: Cook the Spaghetti
Start by bringing a large pot of salted water to a boil. Add the whole wheat spaghetti and cook until just al dente, usually about 8 to 10 minutes. Be careful not to overcook because the pasta will continue to cook in the oven. Drain the spaghetti and set it aside to cool slightly.
Step 2: Prepare the Meat Sauce
Heat the olive oil in a large skillet over medium heat. Add the chopped onion and sauté for about 3 minutes until softened. Toss in the minced garlic and cook for another 30 seconds until fragrant. Next, add the ground turkey or chicken, breaking it up with a spoon, and cook until browned and no longer pink. Stir in the diced tomatoes, tomato paste, oregano, basil, red pepper flakes if using, and season with salt and pepper. Let this simmer gently for about 10 minutes so the flavors meld together beautifully.
Step 3: Combine the Cheeses
In a medium bowl, mix together the low-fat cottage cheese, part-skim ricotta, and half of the shredded mozzarella cheese. This creamy mixture adds protein and a luscious texture to the casserole’s interior.
Step 4: Assemble the Casserole
Preheat your oven to 375°F (190°C). In a large baking dish, layer half of the cooked spaghetti on the bottom. Spread half of the meat sauce over the pasta, then dollop half of the cheese mixture on top and gently swirl it in a bit. Repeat with the remaining spaghetti, sauce, and cheese blend. Sprinkle the remaining mozzarella and the grated Parmesan cheese evenly over the top for a golden, bubbly finish.
Step 5: Bake Until Perfect
Place the assembled casserole into the oven and bake uncovered for about 20 minutes, or until the cheese is melted, bubbling, and lightly browned. Let it cool for a few minutes before serving, so the casserole sets and slices nicely.
How to Serve High Protein Spaghetti Casserole Recipe
Garnishes
A sprinkle of fresh basil or parsley adds a bright, fresh element and a pop of color that makes this dish even more inviting. For a bit of zing, a few extra red pepper flakes or a drizzle of good olive oil can be the finishing touch.
Side Dishes
Keep things light and balanced by pairing this casserole with a crisp green salad tossed in lemon vinaigrette or a simple steamed vegetable like broccoli or green beans. Garlic bread can be an indulgent side if you’re in the mood for something extra cozy.
Creative Ways to Present
For gatherings, serve the casserole in individual ramekins or mini cast iron skillets for a charming presentation. You can also turn leftovers into delicious stuffed bell peppers or layer the casserole components in a glass dish to showcase its vibrant layers.
Make Ahead and Storage
Storing Leftovers
This High Protein Spaghetti Casserole Recipe stores wonderfully in an airtight container in the refrigerator for up to 3 days. The flavors deepen overnight, making leftovers even more delicious.
Freezing
To freeze, cool the casserole completely, then cover tightly with foil or plastic wrap and place into a freezer-safe container. It will keep well for up to 3 months, making it a convenient meal prep option.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes until warmed through, or microwave individual portions for 2 to 3 minutes. Adding a splash of water or broth before reheating keeps the casserole moist and prevents drying out.
FAQs
Can I use a different type of pasta for this High Protein Spaghetti Casserole Recipe?
Absolutely! While whole wheat spaghetti adds extra fiber and protein, you can substitute with chickpea pasta, lentil pasta, or any high-protein variety you prefer. Just be mindful of the cooking time to avoid overcooking.
Is it possible to make this casserole vegetarian?
Yes! Simply swap the ground turkey for plant-based crumbles or cooked lentils, and use vegetarian cheese options. The casserole will still be hearty and flavorful.
Can I double this recipe for a bigger crowd?
Definitely! Just use a larger baking dish or split into two casseroles, and extend the baking time slightly to ensure it’s heated through and the cheese is bubbly and golden.
What can I add to boost the vegetable content?
Great question! Adding chopped spinach, zucchini, or mushrooms into the sauce is an easy way to sneak in more veggies without compromising flavor or texture.
How do I make this recipe lower in fat?
Using lean ground turkey or chicken and low-fat cheeses already keeps the fat content reasonable. You can also reduce the mozzarella topping or omit the Parmesan if desired, and avoid adding extra oil during cooking.
