  • Total time: 60 minutes

Step-by-Step Instructions

Step 1: Prepare Your Ingredients

Begin by setting your oven to 350°F (175°C) and apply a thin layer of oil or cooking spray to a 9×13-inch baking dish. Break the spaghetti into thirds—this creates the perfect bite-sized portions that hold together beautifully when served. Pro tip: Breaking the pasta before cooking prevents awkward long strands that make the casserole difficult to serve and eat.

Step 2: Cook the Pasta

Heat a large pot of water with salt until it reaches a vigorous boil. Cook the spaghetti for 2 minutes less than the package instructions indicate (approximately 6-7 minutes for most brands). This undercooking ensures your spaghetti casserole won’t become mushy during baking. Drain well but don’t rinse—the starch helps bind the casserole.

Step 3: Prepare the Meat Sauce

In a large skillet over medium-high heat, brown the ground beef, breaking it into small crumbles as it cooks. When it’s about halfway done (after about 3-4 minutes), add the chopped onion and continue cooking until the meat is no longer pink and the onions are translucent (approximately 5 more minutes). Drain excess fat, then stir in the marinara sauce and reduce heat to low. Allow the mixture to simmer gently for 5 minutes so the flavors can blend together.

Step 4: Create the Cheese Mixture

In a medium bowl, combine the cottage cheese, 1 cup of the mozzarella, and beaten eggs. This mixture creates the creamy, binding layer that gives your spaghetti casserole its distinctive texture. The eggs help set the casserole while the cheeses provide richness and depth of flavor.

Step 5: Assemble the Casserole

Layer half of the cooked spaghetti in the bottom of your prepared baking dish. Top with half of the cheese mixture, spreading it evenly. Add half of the meat sauce. Repeat these layers, finishing with the remaining meat sauce on top. The layering technique ensures every bite contains the perfect balance of pasta, cheese, and sauce.

Step 6: Add the Final Cheese Layer

Sprinkle the remaining cup of mozzarella cheese evenly over the top of the casserole. This creates that irresistible golden, slightly crispy cheese top that will have everyone reaching for seconds.

Step 7: Bake to Perfection

Bake uncovered in your preheated oven for 30 minutes, or until the casserole is bubbling at the edges and the cheese is melted and beginning to turn golden brown. For an extra golden top, switch to broil for the final 2 minutes, watching carefully to prevent burning.

Step 8: Rest Before Serving

Allow the spaghetti casserole to rest for 10 minutes before cutting. This resting period allows the layers to set, making for cleaner slices and enhanced flavor as the ingredients settle together. A dish that’s rushed to the table straight from the oven will fall apart when served.

Common Mistakes to Avoid

Based on feedback from hundreds of home cooks, these are the most frequent pitfalls when preparing spaghetti casserole:

  1. Overcooking the pasta: Remember to undercook by 2 minutes—it continues cooking in the oven. Surveys show this is the #1 reason for mushy casseroles.
  2. Skipping the resting period: Cutting into the casserole immediately after baking results in a sloppy presentation. The 10-minute rest allows the internal temperature to stabilize and ingredients to set.
  3. Using cold ingredients: Allow refrigerated items like cottage cheese to come to room temperature before mixing. Cold ingredients can lead to uneven cooking and extended baking times.
  4. Under-seasoning: Don’t forget to taste your meat sauce before assembling. Even with prepared marinara, you may need additional herbs or salt to enhance flavor.
  5. Covering the casserole during baking: This creates steam that prevents proper cheese browning and can make the top layer soggy. Leave it uncovered for that desirable golden crust.

Storing Tips for the Recipe

Maximize the convenience of this spaghetti casserole recipe with these storage strategies:

  • For refrigerating: Keep any remaining casserole in a sealed container, where it will stay fresh for up to 4 days. Individual portions in meal-prep containers make for quick lunches or dinners.
  • Freezing: This spaghetti casserole freezes beautifully for up to 3 months. For best results, cool completely before freezing either whole or in portions. Wrap tightly in plastic wrap, then aluminum foil, and label with the date.
  • Reheating: For refrigerated leftovers, microwave individual portions for 2-3 minutes or reheat in a 350°F oven for 15-20 minutes until warmed through. For frozen casserole, thaw overnight in the refrigerator before reheating, or add 20-30 minutes to the reheating time if cooking from frozen.
  • Make-Ahead Option: You can assemble the entire casserole up to 24 hours in advance and refrigerate, covered with plastic wrap. Allow it to sit at room temperature for 30 minutes before baking, and add 5-10 minutes to the baking time.
  • Freshness Tip: To prevent the top from drying out during storage, lightly sprinkle a few drops of water before reheating or place a damp paper towel over the portion when microwaving.
