Zucchini Tomato Pasta Bake Ingredients
Unlock the secret to a cozy, comforting meal with these easy-to-find ingredients!
For the Pasta
- Penne Pasta – Cook al dente to maintain texture and avoid mushiness in your Zucchini Tomato Pasta Bake.
For the Sauce
- Olive Oil – Use extra virgin for a richer flavor while sautéing.
- Yellow Onion – Adds sweetness; shallots are a great substitute for a gentler taste.
- Garlic – Fresh is best for aromatic depth; powdered can save time if needed.
- Red Pepper Flakes (optional) – Add a pinch for some heat, or skip for a milder dish.
- Zucchini – The star ingredient; grate and squeeze out water to keep the bake from getting soggy.
- Crushed Tomatoes – Serve as the sauce base; canned is time-saving, or use fresh for a bright flavor.
- Dried Oregano & Dried Basil – Sprinkle in some herbal notes; fresh herbs can elevate the taste at a 3:1 ratio.
- Heavy Cream (optional) – For a rich, creamy sauce; swap with milk for a lighter option.
For the Cheese
- Mozzarella Cheese – Ideal for that gooey stretch; mix in other cheeses like fontina for added flair.
- Parmesan Cheese – Adds a sharp kick; fresh grated offers superior flavor over pre-grated.
For Seasoning
- Salt & Black Pepper – Essential to enhance the inherent flavors of your dish.
Step‑by‑Step Instructions for Zucchini Tomato Pasta Bake
Step 1: Cook Pasta
Start by boiling a large pot of salted water over high heat. Once boiling, add the penne pasta and cook it al dente according to package instructions, typically around 8-10 minutes. When done, reserve 1 cup of pasta water for later use, then drain the pasta and set it aside, creating a flavorful base for your Zucchini Tomato Pasta Bake.
Step 2: Sauté Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced yellow onion and sauté until translucent, roughly 5-7 minutes. Stir in minced garlic and optional red pepper flakes, cooking for an additional minute until fragrant. Next, add the grated zucchini, stirring occasionally, and cook until softened, about 5-8 minutes, developing a rich foundation for your sauce.
Step 3: Prepare Sauce
To the sautéed vegetables, add the crushed tomatoes, dried oregano, and dried basil. Stir well and bring to a simmer over medium-low heat. Cover the skillet and let it simmer for 15-20 minutes, stirring occasionally. If the sauce thickens too much, use some reserved pasta water to adjust the consistency. For added creaminess, mix in the heavy cream (if using) and season with salt and black pepper.
Step 4: Combine & Layer
Preheat your oven to 375°F (190°C) while you mix the pasta and sauce. In a large mixing bowl, combine the cooked penne with the tomato-zucchini sauce, ensuring even coating. In a greased 9×13-inch baking dish, layer half of the pasta-sauce mixture, followed by half of the mozzarella and Parmesan cheese. Repeat with the remaining pasta and cheese, creating a comforting Zucchini Tomato Pasta Bake filled with gooey goodness.
Step 5: Bake
Place the assembled dish in the preheated oven and bake for 20-25 minutes. Look for the cheese to be bubbling and the top golden brown. If you desire a crispier finish, set the oven to broil for an additional 1-2 minutes, closely monitoring to prevent burning for a delicious crispy top.
Step 6: Rest & Serve
Once baked, remove the Zucchini Tomato Pasta Bake from the oven and let it rest for 10-15 minutes. This resting period allows the flavors to meld and makes it easier to serve. Optionally, garnish each portion with torn fresh basil before plating, enhancing both flavor and presentation for a heartwarming meal everyone will enjoy.
Make Ahead Options
This Zucchini Tomato Pasta Bake is perfect for meal prep enthusiasts looking to save time during busy weeknights! You can prepare the entire dish up to 24 hours in advance. Simply assemble the pasta bake without baking it, cover it tightly with plastic wrap, and refrigerate to maintain freshness. The key to preserving quality is to hold off on adding the cheese until just before baking—this prevents it from becoming soggy. When you’re ready to serve, preheat your oven to 375°F (190°C) and bake the pasta bake for about 25-30 minutes, or until bubbling and golden brown. This way, you’ll enjoy a delicious homemade meal with minimal fuss!
