⏱ Quick Recipe Overview

Prep Time: 15 minutes
Cook Time: 35 minutes
Total Time: 50 minutes
Servings: 6

Ingredients You’ll Need

  • 4 medium zucchinis, sliced into rounds

  • 2 cups shredded cheese (mozzarella + cheddar recommended)

  • 1 cup heavy cream

  • 2 large eggs

  • 1 teaspoon garlic powder

  • 1 teaspoon onion powder

  • Salt and pepper, to taste

  • Fresh herbs (like basil or parsley) for garnish

‍ How to Make It

Step 1: Preheat

Preheat your oven to 350°F (175°C) and grease a casserole dish with butter or oil.

Step 2: Prep the Zucchini

Slice the zucchinis evenly and place them in a colander. Sprinkle with salt and let sit for 15 minutes to remove excess moisture. Pat dry with paper towels.

Step 3: Mix the Creamy Base

In a mixing bowl, whisk together the heavy cream, eggs, garlic powder, onion powder, salt, and pepper.

Step 4: Layer It Up

Add half the zucchini slices to the bottom of your baking dish. Pour half the creamy mixture over the top, then sprinkle with 1 cup of cheese. Repeat with the remaining ingredients, ending with a cheesy top layer.

Step 5: Bake

Bake for 30–35 minutes, until the top is golden and bubbly.

Step 6: Garnish and Serve

Let cool for a few minutes, sprinkle with fresh herbs, and serve warm.

What to Serve It With

This casserole is filling on its own, but it also pairs beautifully with:

  • A fresh green salad with lemon vinaigrette

  • Grilled chicken or baked salmon for added protein

  • Roasted low-carb veggies, like broccoli or cauliflower

  • A glass of sparkling water with lemon for a crisp finish

Light, fresh sides balance out the rich, creamy texture of the casserole perfectly.

Tips for the Perfect Keto Zucchini Casserole

  • Slice Evenly: Thin, uniform zucchini slices ensure even cooking.

  • Don’t Skip Salting: Drawing out moisture prevents a watery casserole.

  • Customize the Cheese: Try Swiss, Parmesan, or pepper jack for extra flavor.

  • Cover If Needed: If the top browns too quickly, cover loosely with foil.

  • Add Protein: Mix in cooked sausage or shredded chicken for a heartier version.

Storing & Reheating

  • Refrigerate: Store leftovers in an airtight container for up to 4 days.

  • Reheat: Warm in the oven at 350°F (175°C) for 10–15 minutes, or microwave individual portions.

  • Freeze: You can freeze before baking (up to 3 months). Thaw overnight before baking as directed.

The flavor only improves as the ingredients meld—making leftovers just as tasty!
