Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 190°C / 375°F.
Lightly grease a large rectangular baking dish if needed and set it aside.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil.
Add the penne and cook according to the package directions, but stop cooking slightly before the pasta becomes completely tender.
The pasta should be al dente because it will continue cooking in the oven.
Drain the pasta well and set it aside.
Step 3: Sauté the Vegetables
Heat the olive oil in a large skillet or sauté pan over medium heat.
Add the finely chopped onion and cook for about 2–3 minutes.
Add the minced garlic, diced green bell pepper, and sliced mushrooms.
Cook for approximately 5–7 minutes, stirring occasionally, until the vegetables begin to soften and the mushrooms release most of their moisture.
Step 4: Brown the Beef
Add the ground beef to the skillet with the vegetables.
Break the beef apart with a wooden spoon or spatula and cook until completely browned.
Season with salt, black pepper, and Italian seasoning.
Continue cooking until the beef is fully cooked and no longer pink.
If there is excessive liquid or fat in the pan, carefully drain some of it before continuing.
Step 5: Add the Tomato Sauce
Pour the tomato sauce or marinara sauce into the skillet.
Stir well to combine the beef, vegetables, and sauce.
Reduce the heat to low and simmer for 5–10 minutes, stirring occasionally.
This allows the flavors to blend and creates a rich, savory sauce for the pasta.
Step 6: Combine the Pasta and Sauce
Add the cooked penne to the skillet.
Gently stir until the pasta is evenly coated with the beef and tomato sauce.
Make sure the sauce is distributed throughout the pasta rather than sitting only on the bottom of the pan.
Step 7: Assemble the Casserole
Transfer the pasta mixture to a large rectangular baking dish.
Spread everything into an even layer.
Sprinkle the shredded mozzarella and cheddar evenly over the entire surface.
For an especially cheesy topping, make sure the cheese reaches all the way to the edges of the casserole.
Step 8: Bake
Place the baking dish in the preheated oven.
Bake at 190°C / 375°F for 15–20 minutes, or until the cheese is completely melted, bubbling, and beautifully golden.
If you want a more deeply browned cheese topping, switch to the broiler for the final 1–2 minutes, watching carefully so the cheese does not burn.
Step 9: Garnish and Serve
Remove the pasta bake from the oven and allow it to rest for about 5 minutes.
Sprinkle freshly chopped parsley over the top.
Serve warm while the cheese is still melted and creamy.
Best Tips
Cook the pasta only until al dente because it will continue cooking while the casserole bakes.
Use a flavorful marinara or tomato sauce for a richer finished dish.
Do not overcrowd the skillet when browning the beef, as this can cause the meat to steam instead of brown.
Sauté the mushrooms until their excess moisture has evaporated to prevent the casserole from becoming watery.
Let the finished pasta bake rest for a few minutes before serving so the sauce can thicken slightly.
For an extra-golden topping, broil the casserole briefly at the end while watching it carefully.
Best Ingredient Options
Penne works particularly well because its shape holds onto the tomato and beef sauce.
You can also use rigatoni, ziti, fusilli, rotini, or another short pasta.
For the beef, ground beef with moderate fat content provides excellent flavor and keeps the casserole moist.
Fresh mushrooms provide a delicious earthy flavor, but canned mushrooms can also be used when needed. Drain them well before adding them to the skillet.
For the cheese, mozzarella and cheddar make a great combination, but you can also add Parmesan, provolone, or Monterey Jack.
Recipe Variations
For a spicy version, add crushed red pepper flakes or a little chili powder to the beef sauce.
For extra vegetables, add diced zucchini, spinach, carrots, or additional bell peppers.
For a creamy pasta bake, stir a small amount of cream cheese or heavy cream into the tomato sauce before combining it with the pasta.
For a stronger Italian-inspired flavor, add oregano, basil, garlic, and a little Parmesan cheese.
You can also add a layer of ricotta underneath the shredded cheese for an extra-creamy casserole.
What to Serve With
Serve this hearty pasta bake with a crisp green salad for a fresh contrast.
Garlic bread or homemade bread is perfect for soaking up the rich tomato sauce.
Roasted vegetables such as zucchini, broccoli, or carrots also make excellent side dishes.
For a lighter meal, serve smaller portions with a simple cucumber and tomato salad.
Make-Ahead Instructions
This casserole is ideal for preparing ahead of time.
Assemble the pasta bake completely, including the cheese topping, then cover it tightly and refrigerate it until you are ready to bake.
When baking directly from the refrigerator, you may need to add several extra minutes to the cooking time.
For the best results, avoid leaving the assembled casserole at room temperature for an extended period before baking.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Store the pasta bake in the refrigerator for up to 3–4 days.
Individual portions are convenient for quick lunches or dinners throughout the week.
Reheating
For individual portions, reheat in the microwave until heated through.
For larger portions, cover the casserole with foil and reheat in a 175°C / 350°F oven until hot.
You can also reheat individual portions in the Air Fryer for a slightly crispier cheese topping.
If the pasta seems dry after refrigeration, add a small splash of tomato sauce or water before reheating.
Freezing
This beef pasta bake can be frozen either before or after baking.
For freezing before baking, assemble the casserole in a freezer-safe baking dish, cover it tightly, and freeze.
For freezing leftovers, divide the casserole into individual portions and store them in airtight freezer-safe containers.
For the best quality, use frozen portions within approximately 2–3 months.
Thaw overnight in the refrigerator before reheating or baking.
Common Mistakes to Avoid
Do not overcook the pasta before baking, because it can become soft and mushy in the oven.
Avoid adding too much liquid to the tomato sauce, as excess moisture can make the casserole watery.
Do not skip sautéing the mushrooms properly, because their released moisture can affect the final texture.
Avoid using too little seasoning in the beef mixture, as the pasta and tomato sauce need enough seasoning for a flavorful result.
Do not cut into the casserole immediately after removing it from the oven. A short resting period helps the layers settle.
