Ingredients You’ll Need
These ingredients are surprisingly simple but each plays a crucial role in crafting the perfect Cheesy Zucchini Squares Recipe — from the creamy Monterey Jack cheese that melts beautifully to the green chiles that add just the right hint of spice and character.
- 5 medium zucchini, diced: Provides a fresh, mild vegetable base that stays tender after baking.
- 2 Tbsp all-purpose flour: Helps bind the ingredients and adds structure to the squares.
- 2 tsp baking powder: Gives a slight lift, ensuring the squares aren’t dense.
- 1 tsp salt: Enhances all the flavors and balances the richness.
- ½ cup milk: Adds moisture and keeps the texture creamy.
- 4 eggs: Acts as a natural binder and adds richness, making the squares firm yet tender.
- 1 (4-oz) can chopped green chiles: Brings a mild spice and a pop of color that complements the zucchini perfectly.
- 4 cups Monterey Jack cheese: The star of the show with its creamy, meltable qualities and mild, buttery flavor.
How to Make Cheesy Zucchini Squares Recipe
Step 1: Prepare Your Oven and Pan
First things first, preheat your oven to 325ºF to get it nice and ready for baking. Grab a 9×13-inch pan and lightly spray it with cooking spray to ensure your cheesy squares don’t stick. This step sets the stage for an easy cleanup and perfect browning.
Step 2: Cook the Zucchini
Bring a large saucepan of water to a boil and drop in your diced zucchini for about 4 minutes. This quick blanching softens the zucchini just enough so that it blends seamlessly into the casserole without becoming mushy. After boiling, drain thoroughly and let it cool for 10 minutes — this step is key to avoid excess moisture that could make the squares soggy.
Step 3: Mix the Batter
In a large bowl, whisk together the flour, baking powder, and salt — these dry ingredients ensure your squares have the right structure. Slowly beat in the milk until smooth, followed by the eggs, which will add roominess and richness. Fold in the chopped green chiles to bring a slight kick of flavor, then gently stir in the zucchini and the shredded Monterey Jack cheese. This combination creates a luscious, cheesy mixture that promises amazing taste and texture.
Step 4: Bake Until Perfect
Pour the batter into the prepared pan, spreading it out evenly. Bake uncovered for 40 to 50 minutes, or until a toothpick inserted in the center comes out clean. The edges will be slightly golden, and the cheese will have formed a delightful crust. This baking time allows the squares to set perfectly while keeping the center tender and cheesy.
How to Serve Cheesy Zucchini Squares Recipe

Garnishes
To elevate your Cheesy Zucchini Squares Recipe, consider topping with a sprinkle of fresh chopped herbs such as parsley or chives. These bright green accents add freshness and a beautiful color contrast to the cheesy golden top. A dollop of sour cream or a scattering of diced tomatoes can add a cool, tangy touch that complements the mellow zucchini and rich cheese.
Side Dishes
This dish pairs beautifully with crisp salads or a light soup, making it a wonderful choice for lunch or dinner. Roasted veggies or a citrusy coleslaw add fresh crunch, balancing the creamy texture of the squares. For a heartier meal, serve alongside grilled chicken or a simple protein to round things out.
Creative Ways to Present
For a fun party idea, cut the zucchini squares into bite-sized pieces and serve them on skewers with cherry tomatoes and olives for a colorful appetizer. Alternatively, layer them in a beautiful serving dish garnished with sliced avocado and a drizzle of your favorite hot sauce for a southwestern-inspired twist. The possibilities are endless, and the Cheesy Zucchini Squares Recipe adapts wonderfully to both casual and elegant settings.
Make Ahead and Storage
Storing Leftovers
Once cooled, store your Cheesy Zucchini Squares in an airtight container in the refrigerator. They will stay fresh for up to 3 days, making them perfect for quick snacks or easy reheated meals throughout the week. The creamy texture holds up well when chilled, so you won’t lose that wonderful flavor.
Freezing
If you want to keep these tasty squares for an extended period, freezing is a great option. Wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag or container. They can be frozen for up to 2 months and thawed overnight in the fridge for an easy, wholesome meal whenever the craving strikes.
Reheating
To enjoy your Cheesy Zucchini Squares Recipe leftovers, reheat them gently in a microwave or oven. For best texture, bake at 350ºF for about 10-15 minutes or until heated through, which helps maintain the crispy edges. Avoid overcooking to keep the cheese melty and delicious.
FAQs
Can I use a different type of cheese in this recipe?
Absolutely! While Monterey Jack is ideal for its meltability and mild flavor, you can experiment with mozzarella, cheddar, or even a combo to create different tastes. Just be mindful that sharper cheeses might alter the balance of flavors.
Is it necessary to boil the zucchini before baking?
Boiling the zucchini briefly helps reduce excess moisture and ensures it softens properly for the right texture. Skipping this step might result in a watery casserole, so it’s best to follow the instructions for the best results.
Can I make this recipe gluten-free?
Yes! Simply substitute the all-purpose flour with a gluten-free flour blend suitable for baking. This swap will keep the texture intact while making the dish friendly for gluten-sensitive diets.
How spicy are the green chiles in this recipe?
The canned chopped green chiles used here are typically mild, adding just a subtle warmth and flavor. If you prefer less heat, you can reduce the amount or choose mild versions, or swap for roasted peppers for a different twist.
Can this recipe be made vegetarian or vegan?
For a vegetarian version, this recipe is already suitable. To make it vegan, you would need to replace the eggs with flax or chia egg substitutes, the milk with plant-based milk, and use vegan cheese. Keep in mind the texture and taste will vary, but it’s definitely doable!
