Ingredients for Zucchini Casserole
-
4 medium zucchinis (sliced into thin rounds)
-
1 small onion (finely chopped)
-
2 cloves garlic (minced)
-
1 cup shredded cheddar cheese (divided)
-
½ cup grated Parmesan cheese
-
1 cup sour cream (or Greek yogurt for a lighter option)
-
2 large eggs
-
1 cup breadcrumbs (panko or regular)
-
2 tbsp butter (melted)
-
1 tbsp olive oil
-
1 tsp dried Italian herbs (oregano, basil, thyme)
-
½ tsp paprika
-
Salt and black pepper (to taste)
-
Fresh parsley (for garnish, optional)
Instructions
-
Prep the zucchini: Preheat oven to 375°F (190°C). Slice zucchini into thin rounds and lightly salt them. Let sit for 10 minutes, then pat dry with paper towels to remove excess moisture.
-
Cook aromatics: In a skillet, heat olive oil. Sauté onion and garlic until softened and fragrant (2–3 minutes).
-
Prepare the creamy mix: In a bowl, whisk together sour cream, eggs, half of the cheddar cheese, Parmesan, herbs, paprika, salt, and pepper. Stir in the cooked onion and garlic.
-
Assemble the casserole: Grease a baking dish. Layer zucchini slices, then spread some creamy mixture over them. Repeat layers until all zucchini is used.
-
Topping: Mix breadcrumbs with melted butter and the remaining cheddar cheese. Sprinkle evenly on top.
-
Bake: Place in preheated oven and bake for 30–35 minutes, until golden brown and bubbly.
-
Serve: Let cool slightly before serving. Garnish with fresh parsley.
Notes
-
Salting the zucchini first helps prevent a watery casserole.
-
You can substitute yellow squash or a mix of both.
-
For extra protein, add cooked ground chicken, turkey, or beef between layers.
-
Gluten-free option: Use almond flour or gluten-free breadcrumbs.
Tips
-
Use a mandoline slicer for evenly thin zucchini slices.
-
If zucchini is very watery, you can lightly roast or sauté slices before layering.
-
Add a pinch of red chili flakes for a spicy kick.
-
For a creamier texture, add ½ cup ricotta or cottage cheese to the mixture.
