How to Make High-Protein Spaghetti Casserole

- Cook the Pasta: Boil the spaghetti according to package instructions until al dente. Drain and set aside.
- Brown the Ground Beef: Heat a skillet over medium heat, then add the ground beef, breaking it up until it’s cooked through. Drain excess fat.
- Mix in the Sauce: Stir in the marinara sauce and Italian herbs with the ground beef until combined.
- Layer the Ingredients: In a large baking dish, first add the cooked spaghetti. Next, spread the meat sauce mixture evenly over the noodles.

Tips for Success
- Don’t Overcook the Pasta: Keep it slightly firm, as it will continue to cook while baking.
- Choose Quality Ingredients: Opt for fresh or high-quality marinara sauce for the best flavor.
- Layer Evenly: Distributing the ingredients evenly helps ensure that every bite is delicious.
- Let It Rest Before Serving: Allow the casserole to cool for a few minutes before cutting; this helps it hold its shape.
Easy Variations

Storage and Reheating

- Freezer Storage: Freeze portions for up to 3 months. Thaw overnight in the fridge before reheating.
- Best Reheating Method: Reheat in the oven at 350°F until heated through, to maintain the cheese’s texture. Alternatively, microwave individual portions, but add a splash of water to keep it moist.
Common Mistakes to Avoid
- Overcooking Ground Beef: Be mindful not to overbrown the beef, which can lead to a dry texture.
