Ingredients Needed
Here’s everything you’ll need for this delightful dish. I’ve included some notes so you know why each ingredient is important:
- Penne pasta (12 ounces / 340g) – Tubular pasta like penne holds the sauce beautifully, ensuring every bite is saucy and flavorful.
- Olive oil (2 tablespoons) – For sautéing vegetables; it adds a subtle fruity richness.
- Garlic (3 cloves, minced) – Aromatic powerhouse that builds depth in the sauce.
- Onion (1 medium, finely chopped) – Adds sweetness and texture.
- Bell peppers (1 red, 1 yellow, chopped) – Brightens the dish with color and natural sweetness.
- Zucchini (1 medium, diced) – Softens in the sauce while absorbing flavor.
- Mushrooms (1 cup, sliced) – Adds an earthy, umami depth.
- Tomato sauce (24 ounces / 680g) – The base of your dish; choose a high-quality sauce or homemade for the best taste.
- Diced tomatoes (14.5 ounces / 410g, canned) – Adds freshness and a slight tang.
- Italian seasoning (2 teaspoons) – A classic blend of herbs that amplifies flavor.
- Red pepper flakes (optional, ¼ teaspoon) – A subtle kick without overpowering.
- Salt and black pepper (to taste) – Balances and enhances all the flavors.
- Mozzarella cheese (2 cups, shredded) – For gooey, melty indulgence.
- Parmesan cheese (½ cup, grated) – Adds sharp, nutty complexity and helps form a golden crust.
- Fresh basil (optional, for garnish) – For freshness and a hint of herbal brightness.
Cooking Instructions
Here’s where the magic happens. Follow these steps carefully for the ultimate baked penne experience:
- Preheat the oven to 375°F (190°C). This ensures your pasta bakes evenly.
- Cook the pasta: Boil penne in salted water until al dente, about 1-2 minutes less than package directions. Drain and set aside.
-
Sauté The Vegetables
- Heat olive oil in a large skillet over medium heat.
- Add onions and garlic, cooking until translucent and fragrant.
- Toss in bell peppers, zucchini, and mushrooms. Cook until slightly tender, about 5-6 minutes.
-
Prepare The Sauce
- Stir in tomato sauce and diced tomatoes.
- Add Italian seasoning, red pepper flakes, salt, and pepper.
- Let the sauce simmer for 5-10 minutes so the flavors meld beautifully.
-
Combine Pasta And Sauce
- Mix cooked penne with the sauce and vegetables until evenly coated.
-
Assemble The Casserole
- Grease a 9×13-inch baking dish lightly.
- Pour half the pasta mixture into the dish.
- Sprinkle half the mozzarella and parmesan cheeses.
- Layer the remaining pasta on top and finish with remaining cheese.
-
Bake To Perfection
- Cover with foil and bake for 20 minutes.
- Remove foil and bake an additional 10-15 minutes, or until cheese is bubbly and golden.
-
Garnish And Serve
- Sprinkle fresh basil on top before serving.
- Let it rest for 5 minutes to set-this helps with clean serving and flavor melding.
Ingredient Science Spotlight
Let’s geek out a little-why these ingredients work so beautifully together:
- Tomatoes – High in umami compounds like glutamate, making the sauce rich and savory. Cooking releases their natural sweetness.
- Cheese – Mozzarella melts into creamy stretches, while Parmesan adds a concentrated nutty flavor and contributes to browning via the Maillard reaction.
- Vegetables – Bell peppers, zucchini, and mushrooms absorb flavors and release water that blends with the sauce, creating a luscious texture.
- Pasta – Al dente pasta provides structure, so it doesn’t turn mushy during baking.
Expert Tips
- Don’t overcook the pasta: Remember it will continue to cook in the oven.
- Use fresh herbs if possible: Basil, oregano, or parsley elevate the flavor dramatically.
- Cheese layering: For maximum gooeyness, layer cheese between pasta layers, not just on top.
- Rest before serving: It allows the sauce to thicken and flavors to meld.
Recipe Variations
- Vegan option: Swap mozzarella and Parmesan for vegan cheese alternatives or cashew cream.
- Protein boost: Add cooked chickpeas, lentils, or tofu cubes for added protein.
- Extra veggie-packed: Include spinach, eggplant, or roasted butternut squash for more variety.
- Spicy twist: Add more red pepper flakes or diced jalapeño for heat.
