Step-by-Step Instructions for the Best Spaghetti Casserole Recipe
1. Prepare the Pasta
First and foremost, boil the spaghetti until it is al dente—firm but not overcooked. Then, toss it with olive oil to prevent sticking.
2. Make the Sauce
While the pasta cooks, brown the ground meat in a large skillet. Afterward, add garlic and onion, allowing them to become fragrant. Subsequently, stir in the tomato sauce, season with herbs, and let it simmer for 10-15 minutes.
3. Assemble the Casserole
At this point, preheat your oven to 375°F (190°C). Grease a baking dish to prevent sticking. Then, layer the sauce, spaghetti, and cheese in the dish. Repeat until all ingredients are used, finishing with a generous cheese layer.
4. Bake
Finally, cover the dish with foil and bake for 25 minutes. Then, remove the foil and bake for another 10 minutes until the cheese is bubbly and golden.
Variations to Elevate Your Spaghetti Casserole Recipe
Vegetarian Option
For instance, you can replace meat with vegetables such as mushrooms or bell peppers. Furthermore, using vegan cheese creates a plant-based version of the dish.
Low-Carb Alternative
Replace spaghetti with zucchini noodles or spaghetti squash for a keto-friendly twist. Additionally, opt for a sugar-free marinara sauce to keep it low-carb.
Spicy Twist
If you enjoy a little heat, add red pepper flakes or spicy sausage to the sauce. On the other hand, jalapeños can be an exciting addition for a bold kick.
Tips for Achieving the Perfect Spaghetti Casserole
Use Fresh Ingredients
Fresh garlic and high-quality cheese, for example, make a noticeable difference in flavor.
Avoid Overcooking the Pasta
Cooking the pasta until al dente is crucial for the best texture.
Allow the Casserole to Rest
Let the dish sit for 10-15 minutes before serving. This ensures better layers and enhances the overall experience.
Storing and Reheating Spaghetti Casserole Recipe
Storage
After making the casserole, store leftovers in an airtight container in the refrigerator for up to four days. Alternatively, freeze the uncooked dish for up to three months.
Reheating
To reheat, thaw frozen casserole in the fridge overnight. Then, bake at 350°F (175°C) until thoroughly heated, covering with foil to retain moisture.
