-
Olive Oil
For sautéing the veggies and adding richness to the base of the sauce.
-
Yellow Onion & Garlic
These aromatics create a flavorful foundation. Their sweetness and savoriness add complexity to the sauce.
-
Bell Peppers (Red, Green, Or Yellow)
These vibrant veggies contribute color and a sweet crunch. They also absorb the sauce beautifully.
-
Zucchini
Zucchini adds moisture and texture to the dish, complementing the other veggies and making the bake extra juicy.
-
Mushrooms
The umami-rich mushrooms bring an earthy flavor that balances the dish perfectly.
-
Spinach
A handful of fresh spinach is an easy way to sneak some greens into the meal without overpowering the flavor. Plus, it wilts perfectly into the sauce.
-
Marinara Sauce
Use your favorite store-bought marinara or homemade sauce. It’s the backbone of this dish, and its tanginess and depth bring everything together.
-
Ricotta Cheese
Ricotta adds a smooth, creamy texture to the bake. It’s light yet rich, giving the dish a velvety feel.
-
Mozzarella Cheese
The mozzarella will melt beautifully, forming a gooey, stringy topping. You can use part-skim or whole milk mozzarella depending on your preference.
-
Parmesan Cheese
A sprinkle of parmesan adds a salty, nutty depth to the top of the bake. It crisps up nicely in the oven.
-
Salt, Pepper, And Red Pepper Flakes
These basic seasonings help balance the flavor and add a hint of heat if you like a little spice.
-
Fresh Basil (Optional)
Fresh basil is an excellent garnish that adds a pop of color and a fragrant note to the dish right before serving.
Cooking Instructions
Cooking a Vegetarian Spaghetti Bake is pretty simple, and most of the magic happens in the oven. Follow these steps for a foolproof, comforting meal:
-
Preheat The Oven
Set your oven to 375°F (190°C) to ensure it’s hot and ready for the baking magic.
-
Cook The Spaghetti
In a large pot, cook your spaghetti according to the package directions. Drain and set aside. Remember to toss a little olive oil into the pasta to prevent it from sticking.
-
Sauté The Vegetables
In a large skillet, heat 1-2 tablespoons of olive oil over medium heat. Add the chopped onions and garlic, cooking until they soften and become fragrant (about 2-3 minutes). Next, toss in the bell peppers, zucchini, and mushrooms. Sauté for an additional 5-7 minutes until everything is tender and the vegetables begin to caramelize. Season with salt, pepper, and red pepper flakes to taste. Stir in the spinach until wilted, about 2 minutes.
-
Mix The Sauce
Once your veggies are cooked, pour in the marinara sauce, and let it simmer for about 5 minutes to meld the flavors. Taste and adjust the seasoning if needed.
-
Combine Pasta And Sauce
In a large mixing bowl, combine the cooked spaghetti with the veggie-marina mix. Stir in ricotta cheese until well incorporated.
-
Assemble The Bake
Transfer everything into a greased 9×13-inch baking dish. Top with shredded mozzarella and a sprinkle of parmesan.
-
Bake To Perfection
Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the cheese is bubbly, golden, and slightly browned at the edges.
-
Garnish And Serve
Remove from the oven and sprinkle fresh basil on top (optional). Let the dish cool for 5-10 minutes before serving.
Ingredient Science Spotlight
Every ingredient in this vegetarian bake plays a crucial role, both in flavor and texture. Here’s a quick breakdown of the science behind the stars of this dish:
-
Spaghetti
Pasta serves as the perfect vessel for holding sauce. Its starchy exterior binds to the marinara, making each bite flavorful and satisfying.
-
Vegetables
The variety of vegetables-bell peppers, zucchini, mushrooms, and spinach-not only add texture but also different levels of moisture. Mushrooms, for instance, release water as they cook, enriching the sauce with a savory umami flavor, while zucchini brings a slight crunch and freshness.
-
Cheese
Ricotta’s high moisture content gives it a creamy, light texture that melds with the other ingredients. Mozzarella’s stretching and melting properties are what make the dish so gooey, while parmesan contributes a sharp, nutty contrast.
-
Marinara Sauce
The acidity from tomatoes balances the richness of the cheese and vegetables. The long simmering process in marinara sauce allows the flavors to deepen, creating a complex, savory base.
