Ingredients

Makes 6 generous servings

For the Vegetable Base

• 2 tablespoons olive oil
• 1 large yellow onion, chopped
• 3 cloves garlic, minced
• 1 large red bell pepper, deseeded and chopped
• 1 large green bell pepper, deseeded and chopped
• 1 large zucchini, chopped into half-moons
• 8 ounces cremini mushrooms, sliced
• 5 ounces fresh spinach, roughly chopped
• 1 teaspoon dried oregano
• 1/2 teaspoon dried basil
• 1/4 teaspoon dried thyme
• Salt and black pepper to taste

For the Sauce & Topping

• 1 (28-ounce) can crushed tomatoes
• 1/2 cup vegetable broth
• 1 tablespoon tomato paste
• 1 teaspoon sugar (optional, to balance acidity)
• 1 cup shredded mozzarella cheese
• 1/4 cup grated Parmesan cheese
• Fresh parsley, chopped, for garnish (optional)

Step-by-Step Instructions

1. Step 1: Sauté the Aromatics

   Preheat your oven to 375°F (190°C). Heat the olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add the chopped onion and cook until softened, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant.

   Small tip: Use a pan that can go from stovetop to oven to minimize dishwashing!

2. Step 2: Add Bell Peppers and Zucchini

   Stir in the chopped red and green bell peppers. Cook for about 5 minutes until they start to soften slightly. Next, add the chopped zucchini and sliced mushrooms. Continue to cook for another 5-7 minutes, stirring occasionally, until the vegetables are tender-crisp.

   Small tip: Don’t overcrowd the pan; cook vegetables in batches if your skillet isn’t large enough to ensure they brown instead of steam.

3. Step 3: Season the Vegetables

   Season the vegetables with dried oregano, basil, thyme, salt, and black pepper. Stir well to coat all the vegetables with the herbs and spices. This step builds the foundational flavor of your casserole.

4. Step 4: Incorporate the Spinach and Sauce

   Add the fresh spinach to the skillet. Cook, stirring gently, until the spinach wilts down completely, which usually takes only 2-3 minutes. Pour in the crushed tomatoes, vegetable broth, and tomato paste. Add the optional sugar if using.

   Small tip: The sugar helps cut the acidity of the tomatoes, enhancing the overall flavor of the sauce.

5. Step 5: Simmer the Casserole Base

   Bring the mixture to a gentle simmer. Reduce the heat to low and let it cook for about 5-7 minutes, allowing the flavors to meld together. Stir occasionally to prevent sticking.

6. Step 6: Add Cheese Topping

   Remove the skillet from the heat. Evenly sprinkle the shredded mozzarella cheese over the top of the vegetable mixture. Then, sprinkle the grated Parmesan cheese over the mozzarella for an extra layer of flavor.

7. Step 7: Bake the Casserole

   Carefully transfer the skillet to your preheated oven. Bake for 20-25 minutes, or until the cheese is melted, bubbly, and lightly golden brown. The edges of the casserole should also be bubbling.

   Small tip: If your cheese isn’t browning enough, you can turn on the broiler for the last 1-2 minutes, but watch it very closely to prevent burning.

8. Step 8: Rest and Serve

   Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the casserole to set slightly and makes it easier to scoop. Garnish with fresh parsley, if desired, and enjoy!

Tips & Variations

• Gluten-Free Option: This recipe is naturally gluten-free! Just ensure that your vegetable broth is certified gluten-free. No special substitutions are needed.
• Vegan Option: To make this casserole completely vegan, simply swap the mozzarella and Parmesan cheese for your favorite plant-based shredded mozzarella and a vegan Parmesan alternative. Nutritional yeast can also add a cheesy flavor.
• Add More Vegetables or Protein: Feel free to customize with other vegetables like diced carrots, sweet potatoes, or cauliflower florets. For added protein, stir in a can of drained and rinsed chickpeas or lentils during Step 4.
• Spicy Version: If you love a kick, add 1/2 teaspoon of red pepper flakes along with the other dried herbs in Step 3. You could also finely chop a jalapeño and sauté it with the bell peppers.
• Herb Variations: Experiment with fresh herbs! A sprinkle of fresh rosemary or thyme sprigs baked into the casserole can add a wonderful aroma and depth of flavor. You can also swap the dried herbs for 1 tablespoon of an Italian seasoning blend.
