This creamy and savory Zucchini Tomato Casserole is so incredibly simple to make, and it’s the perfect way to enjoy a garden’s summer veggies. After a short stint in the oven, you’ll be dishing out a vibrant and tasty meal that could stand alone or complement any main dish.

The star players, zucchini and tomatoes, bring a natural juiciness to this dish. The tomatoes provide a balance of sweet and tangy that goes perfectly well with the creamy zucchini.

How To Make Zucchini Casserole

I’ve realized that if I want this family to enjoy veggies more often, I must pair those veggies with cheese! 💡

Ingredients

• Zucchini: Use smaller zucchini – they are tastier and have less seeds.
• Tomatoes: I like to use heirloom tomatoes in this recipe.
• garlic, herbs, and seasonings
• whipped cream cheese, milk, & shredded cheese.

Directions

• We start with slicing up around 2 average-sized zucchinis and two large heirloom tomatoes. Slices of both veggies should be around 1/4-inch thick.
• In a 9-inch baking dish layer the zucchini slices and then the tomato slices. In between each layer, sprinkle the tomatoes with fresh basil and garlic. Sprinkle the zucchini with salt and fresh ground pepper.
• Combine cream cheese and milk in a bowl and whisk in a pinch of nutmeg, and Italian Seasoning. Add a layer of the cream cheese mixture over the tomatoes and sprinkle with shredded Italian blend cheese or mozzarella cheese. You can use whatever type of shredded cheese you have on hand.
• Continue with one more layer of zucchini and lastly a layer of tomatoes. Spread the remaining layer of cream cheese mixture and add more cheese.
• Bake for 25 minutes, or until bubbly, browned, and veggies are tender.
• Let stand 10 minutes in room temperature before cutting and serving.

Tips & Add Ins

• Zucchini and tomatoes will release water during baking, and that’s completely normal. 
• If you don’t want to bother with adding salt, pepper, garlic, and basil in between layers, you can just mix them in with the cream cheese blend. 
• For those that like a softer veggie, keep the dish in the oven for an extra 7 to 10 minutes. If you see that it’s browning too much on the top while baking, loosely cover it with foil while continuing to bake. 
• Choosing Zucchini: Smaller zucchinis are usually more flavorful and have fewer seeds. They are a great choice for this casserole if you can find them.
• Adjust the Creaminess: If you like casseroles extra creamy, consider adding more cream cheese or even a dollop of sour cream.
• Add Protein: To make a complete meal, add some cooked chicken or ground turkey to the mix.
• Cheese: Feel free to play around with the types of cheese you use. Mozzarella, Parmesan, or even a sharp cheddar could work wonderfully.
• Pre-cook The Veggies: To reduce the amount of water in your finished dish, you can lightly sauté your zucchini and tomatoes before adding them to your casserole.
• Add Crunch: For a crunchy topping, sprinkle the top of your casserole with some breadcrumbs, pork rind crumbs, or crushed buttery crackers before popping it in the oven.

Serving Suggestions

This Zucchini Tomato Casserole is a must-try for its simple yet delicious blend of fresh vegetable flavors. It’s the perfect way to add some variety to your table and trust me, it’ll leave your taste buds craving for more. Here are some ideas to serve the casserole with:

• Honey Soy Grilled Pork Chops
• Air Fryer Steak
• Instant Pot Chicken Breasts
• Lemon Butter Grilled Salmon

Storing Leftovers

• Store in airtight containers and keep in the fridge for up to 3 days. Makes for a delicious and quick work lunch! 
• I don’t recommend freezing it because zucchini and tomatoes both release a lot of water, and that will affect the taste and texture of the overall dish.
