Ingredients

Here’s what you’ll need for your High Protein Spaghetti Casserole:

Spaghetti: The classic pasta that serves as the base of the dish. You can use whole wheat or gluten-free spaghetti for a healthier twist.

Lean Ground Meat (Turkey or Chicken): This is where the protein comes in. Lean turkey or chicken adds tons of flavor and helps make this casserole extra filling.

Marinara Sauce: The rich, tomatoey sauce that ties everything together. Go for a low-sodium version to keep things healthier, or make your own from scratch for a more personal touch.

Ricotta Cheese: Creamy and smooth, ricotta adds richness to the casserole and complements the pasta perfectly.

Mozzarella Cheese: This melty, gooey cheese adds that perfect layer of cheesy goodness on top.

Parmesan Cheese: A sprinkle of parmesan brings an extra level of savory flavor to the dish.

Eggs: Eggs help bind everything together and give the casserole its structure.

Italian Seasoning: A blend of dried herbs like basil, oregano, and thyme adds an aromatic touch to the dish.

Salt and Pepper: The essentials to bring out the flavors. You can adjust to taste!

Instructions

Let’s get this casserole going!

1. Preheat the Oven:
Preheat your oven to 375°F (190°C). This gives your casserole the perfect heat to cook through and get that crispy, cheesy top.

2. Cook the Spaghetti:
Cook the spaghetti according to the package instructions, but make sure to undercook it slightly since it will continue cooking in the oven. Drain and set aside.

3. Brown the Meat:
In a large skillet, heat a little olive oil over medium heat. Add the ground turkey or chicken and cook until browned and cooked through, breaking it up into small pieces as it cooks. Drain any excess fat.

4. Mix the Sauce:
In a large bowl, combine the marinara sauce with ricotta cheese, eggs, and half of the mozzarella. Add the cooked meat and season with Italian seasoning, salt, and pepper. Stir until everything is well combined.

5. Assemble the Casserole:
In a large baking dish, layer half of the cooked spaghetti. Top with half of the meat and sauce mixture. Repeat with the remaining spaghetti and sauce. Finish by sprinkling the rest of the mozzarella and the parmesan on top.

6. Bake:
Cover the casserole with foil and bake in the preheated oven for 20-25 minutes. Then, remove the foil and bake for another 10-15 minutes, or until the cheese is melted and bubbly and the top is slightly golden.

7. Serve and Enjoy:
Let the casserole cool for a few minutes before serving. Garnish with fresh basil or parsley, if desired.

How to Serve High Protein Spaghetti Casserole

This dish is hearty enough to stand on its own, but here are a few ways to complement it:

Green Salad: A simple green salad with a light vinaigrette adds freshness to balance the richness of the casserole.

Garlic Bread: A slice of warm, crispy garlic bread is always a crowd-pleaser when paired with pasta dishes.

Steamed Vegetables: Serve it alongside some steamed veggies like broccoli or green beans for added color and nutrients.

Roasted Vegetables: Roasted zucchini, bell peppers, or Brussels sprouts can add a savory side that pairs beautifully with this dish.

Wine Pairing: If you’re in the mood for wine, a glass of red wine (like a medium-bodied Merlot) would pair nicely with the tomato-based casserole.

Additional Tips

Here are some pro tips to help make your casserole even better:

Substitute with Ground Beef: If you don’t want to use turkey or chicken, you can absolutely go with lean ground beef or even a meatless option like lentils.

Make It Your Own: Add more veggies like spinach, mushrooms, or bell peppers for extra nutrients. You can even sneak in some chopped carrots or zucchini into the meat sauce.

Leftovers: This casserole stores beautifully! Just refrigerate the leftovers in an airtight container for up to 3 days, or freeze them for up to a month. Reheat in the oven to get that bubbly, cheesy texture back.

Cheese Lovers: If you love cheese, feel free to add extra mozzarella or sprinkle some feta on top before baking.

Make It Gluten-Free: Use gluten-free pasta to make this casserole gluten-free. It’s an easy swap that doesn’t compromise on flavor.
