Ingredient Notes & Details

Zucchini
Choose firm, fresh zucchini with bright skin.
Slice evenly so they bake consistently.

Cheese
Cheddar, mozzarella, or Gruyère work beautifully.
For extra flavor, mix two cheeses together.

Cream
Heavy cream gives the richest texture.
For a lighter version, use half-and-half.

Butter
Butter adds a silky richness to the sauce.
Use unsalted butter so you can control the salt.

Flour
Flour helps thicken the sauce into a creamy consistency.
For a low carb version, use almond flour or a keto thickener.

Garlic
Fresh garlic adds warmth and depth.
Use minced garlic for best flavor.

Onion
Onion adds sweetness and aroma.
Finely dice it so it blends into the sauce.

Salt & Pepper
Season gradually and taste as you go.
You want the flavors balanced—not overly salty.

Nutmeg (optional)

It adds a subtle warmth without being overpowering.

Step-by-Step Instructions

Preheat the oven
Set your oven to 375°F (190°C).
Grease a baking dish with butter or non-stick spray.

Slice the zucchini
Cut zucchini into thin, even slices (about 1/8-inch thick).
Even slices help them bake evenly and stay tender.

Make the creamy sauce
In a saucepan, melt butter over medium heat.
Add onions and garlic, cooking until soft and fragrant (about 3–4 minutes).

Thicken the sauce
Sprinkle in flour and whisk for 1 minute.
Gradually add cream while whisking constantly until smooth.

Add cheese
Stir in grated cheese until melted and creamy.
Season with salt, pepper, and a pinch of nutmeg if desired.

Layer the zucchini
Arrange zucchini slices in the baking dish in overlapping layers.
Pour the cheese sauce evenly over the zucchini.

Bake until golden
Cover with foil and bake for 20 minutes.
Remove foil and bake an additional 15–20 minutes until bubbly and golden.

Cool and serve
Let it rest for 5–10 minutes before serving.
This helps the sauce thicken slightly and makes it easier to slice.
