The Key Ingredients You’ll Need
This recipe relies on simple, fresh ingredients to create its wonderful flavor. Here’s what you’ll need to gather:
- Zucchini: The star of the show! Medium-sized zucchini work best as they have fewer seeds and less water content.
- Tomatoes: Ripe, juicy tomatoes are essential. Roma tomatoes are a great choice because they are less watery, but any variety will work.
- Onion and Garlic: These aromatics form the savory base of our sauce, providing a deep, rich flavor.
- Marinara Sauce: Use your favorite store-bought or homemade marinara to bring everything together.
- Cheeses: A blend of mozzarella and Parmesan is key. Mozzarella provides that glorious, cheesy pull, while Parmesan adds a sharp, salty kick.
- Italian Seasoning: A simple blend of dried herbs like oregano, basil, and thyme enhances the Italian-inspired flavors.
- Olive Oil: For sautéeing the aromatics and adding richness.
- Salt and Pepper: To taste.

How to Make The Perfect Tomato Zucchini Coodle
Making this delicious Tomato Zucchini Coodle is as easy as layering and baking. Follow these simple steps for a perfect result.
Step 1: Prepare the Vegetables
First, wash and slice your zucchini and tomatoes into ¼-inch thick rounds. To prevent a watery casserole, it’s crucial to draw out excess moisture from the zucchini. Place the zucchini slices on a baking sheet lined with paper towels, sprinkle them lightly with salt, and let them sit for about 20-30 minutes. You’ll see beads of water form on the surface. Blot them dry with more paper towels. This extra step makes a huge difference!
Step 2: Create the Savory Base
While the zucchini sweats, heat the olive oil in a skillet 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. Stir in the marinara sauce and Italian seasoning. Let it simmer for a few minutes to allow the flavors to meld, then season with salt and pepper to taste.
Step 3: Assemble and Bake the Coodle
Preheat your oven to 375°F (190°C). Spread a thin layer of the marinara sauce on the bottom of a 9×13-inch baking dish. Arrange a single layer of zucchini slices, slightly overlapping. Top with a layer of tomato slices. Spoon about a third of the remaining sauce over the top, then sprinkle with a third of the mozzarella and Parmesan cheese. Repeat the layers two more times. Finish with a generous layer of cheese on top. Bake for 30-35 minutes, or until the top is golden brown and the sauce is bubbly. Let it rest for 10 minutes before serving to allow it to set.
Expert Tips for Success
Want to ensure your casserole is absolutely perfect? Here are a few tips from our kitchen.
- Don’t Skip Salting the Zucchini: This is the most important step for avoiding a soggy dish. It draws out excess water for a perfectly textured bake.
- Use Freshly Grated Cheese: Pre-shredded cheeses often contain anti-caking agents that can prevent them from melting smoothly. Grating your own block cheese makes a world of difference.
- Let it Rest: Allowing the Tomato Zucchini Coodle to rest for at least 10 minutes after baking is essential. This helps the layers set, making it much easier to slice and serve.
Delicious Variations to Try
This recipe is a fantastic starting point. Feel free to customize it with these tasty additions!
- Add Protein: Brown some ground turkey, Italian sausage, or shredded chicken and add it to the sauce for a heartier meal.
- Incorporate More Veggies: Sliced mushrooms, bell peppers, or eggplant would be wonderful additions. Sauté them with the onions before adding to the sauce.
- Spice It Up: Add a pinch of red pepper flakes to the sauce for a little bit of heat.
- Fresh Herbs: Stir in some freshly chopped basil or parsley at the end for a burst of fresh flavor. If you love fresh herbs, you might also enjoy this Lemon Herb Quinoa Salad.
What to Serve With Your Coodle
This Tomato Zucchini Coodle is fantastic on its own, but it also pairs wonderfully with a variety of sides. For a complete meal, serve it alongside some crusty homemade garlic knots to soak up the delicious sauce. A simple green salad or some roasted asparagus also makes a great companion.
