Ingredients You’ll Need

Gathering simple, fresh ingredients is the secret to making this casserole shine. Each component adds its own essential touch—whether it’s creaminess, tang, or a savory crunch—resulting in a dish that’s satisfying and beautifully balanced.

• 4 medium zucchinis: The star of the dish, providing fresh, tender texture and a mild flavor that soaks up all the other ingredients.
• 1 medium onion: Adds subtle sweetness and depth once sautéed to soften and caramelize.
• 2 cloves garlic: Minced for a fragrant boost that wakes up the taste buds.
• 1 cup cherry tomatoes: Halved for pops of juicy acidity that brighten every bite.
• 1 cup shredded cheddar cheese: Sharp, melted cheddar creates gooey richness throughout the casserole.
• 1/2 cup shredded mozzarella cheese: Brings a stretchy, creamy texture that complements the cheddar perfectly.
• 1/2 cup cooked bacon, crumbled: Crispy, smoky bacon adds a savory crunch and depth of flavor.
• 1/4 cup grated Parmesan cheese: Sprinkled on top for a nutty, golden crust that makes the casserole irresistible.
• 1/2 cup sour cream or Greek yogurt: Provides tangy creaminess to bind the ingredients together.
• 1/4 cup mayonnaise: Adds moisture and richness, keeping the casserole lush and decadent.
• 1 tsp Italian seasoning: A savory herb blend that enhances the zucchini and tomato flavors.
• 1/2 tsp smoked paprika: Introduces a subtle smoky warmth that rounds out the spices.
• Salt and pepper: To taste, awakening all the flavors while seasoning the vegetables perfectly.
• 2 tbsp olive oil: For sautéing, bringing everything together with a smooth, fruity base.
• Fresh parsley or chives: Chopped for a bright, fresh garnish that lifts the whole dish visually and in flavor.

How to Make Loaded Zucchini Casserole Recipe

Step 1: Preheat Your Oven

Start by heating your oven to 375°F (190°C). This ensures your casserole bakes evenly and you get that perfectly melted, golden cheese topping you’re dreaming of.

Step 2: Sauté the Aromatics

Heat the olive oil in a skillet over medium heat, then toss in the diced onion and minced garlic. Sauté them until soft and fragrant—about 5 minutes. This simple step layers in fantastic flavor that forms the casserole’s foundation.

Step 3: Cook the Zucchini

Add your fresh zucchini to the skillet and cook for around 5 to 7 minutes until tender but still holding their shape. Season with salt, pepper, Italian seasoning, and smoked paprika. This seasoning blend turns the zucchini into a flavorful, savory vegetable medley.

Step 4: Mix the Casserole Ingredients

Transfer the zucchini mixture to a large bowl, then stir in the cherry tomatoes, sour cream or Greek yogurt, mayonnaise, and half of your shredded cheddar and mozzarella. Mix gently until everything is thoroughly combined—the mixture should be creamy with just the right amount of cheese melted in.

Step 5: Add the Bacon

Fold the crumbled bacon into the vegetable and cheese mix carefully to distribute it evenly. Those crispy, smoky bits add so much delightful texture and flavor to the casserole.

Step 6: Assemble the Casserole

Grease a casserole dish, then pour in your vibrant mixture, spreading it out evenly. Top with the remaining cheddar, mozzarella, and a generous sprinkle of Parmesan cheese. This final cheesy layer is what makes the Loaded Zucchini Casserole Recipe truly special.

Step 7: Bake to Perfection

Place your casserole in the preheated oven and bake for 25 to 30 minutes. Watch as the cheese melts, bubbles, and browns beautifully, signaling your casserole is ready to come out.

Step 8: Cool and Serve

When you take the casserole out of the oven, let it sit for a few minutes. This step helps it set slightly, so when you scoop out servings, they hold together nicely rather than being too runny.

Step 9: Garnish and Enjoy Loaded Zucchini Casserole Recipe

Finally, sprinkle chopped parsley or chives on top for a fresh burst of flavor and color. Serve your warm, cheesy Loaded Zucchini Casserole and watch how quickly it disappears from the table!

How to Serve Loaded Zucchini Casserole Recipe

Garnishes

Adding fresh herbs such as parsley or chives gives the casserole an inviting pop of green and a subtle flavor lift. A light sprinkle of extra Parmesan on top can also elevate the presentation and add a touch more savory punch.

Side Dishes

This casserole pairs wonderfully with a simple green salad tossed in a zesty vinaigrette to cut through the richness. Roasted garlic bread or a fresh tomato salad also complement the hearty texture and creamy cheese perfectly for a full meal.

Creative Ways to Present

For a fun twist, try spooning the casserole into individual ramekins for personal servings. Another idea is to layer it with cooked quinoa or rice for extra texture and a hearty element that stretches the dish for larger gatherings.

Make Ahead and Storage

Storing Leftovers

Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. It’s a perfect make-ahead dish that tastes great when warmed up for lunch or dinner the next day.

Freezing

You can freeze this zucchini casserole uncooked or after baking. Wrap tightly with foil and place in the freezer for up to 2 months. Thaw overnight in the fridge before baking or reheating to maintain the best texture and flavor.

Reheating

Reheat leftovers in the oven at 350°F (175°C) until warmed through and bubbly, about 15-20 minutes. Using the oven keeps the cheesy topping nice and melty compared to microwaving, which can sometimes make it soggy.

FAQs

Can I substitute the bacon for a vegetarian option?

Absolutely! You can replace bacon with smoked tempeh or mushrooms sautéed with smoked paprika to keep that smoky flavor while making it vegetarian-friendly.

Is Greek yogurt a good substitute for sour cream in this recipe?

Yes, Greek yogurt works beautifully, adding a similar tangy creaminess but with fewer calories and more protein, making the casserole a bit lighter without sacrificing flavor.

Can I make this casserole gluten-free?

Definitely! All the ingredients in the Loaded Zucchini Casserole Recipe are naturally gluten-free, so just double-check your seasoning blends and mayonnaise labels to ensure no hidden gluten.

What if I don’t have cherry tomatoes on hand?

Regular tomatoes, diced, work well as a substitute. If they’re very juicy, just gently pat them dry with paper towels to avoid extra moisture in your casserole.

Can this casserole be turned into a vegetarian main dish?

Yes, simply omit the bacon and add extra veggies or plant-based protein like cooked lentils or beans to keep it hearty and satisfying.
