Fresh Ingredients That Make the Dish Shine

The best part of making a corn and squash casserole is how simple, wholesome ingredients come together in one bubbling dish. Quality ingredients are key to creating flavors that stand out. Using fresh spinach and squash brings a garden-fresh taste, while corn adds natural sweetness and texture. Below is a clear ingredient breakdown to guide your shopping and prep:

Ingredient	Amount	Notes/Options
Fresh spinach	6 cups (about 8 oz)	Baby spinach or regular spinach, chopped
Yellow squash or zucchini	3 medium (about 4–5 cups sliced)	Mix both for color variation
Fresh corn kernels	2 cups (about 3–4 ears)	Can substitute frozen, thawed if needed
Onion	1 medium, finely diced	Sweet or yellow onion works best
Garlic	3 cloves, minced	Enhances savory depth
Olive oil	2 tbsp	For sautéing vegetables
Eggs	2 large	Helps bind the casserole
Milk or cream	1 cup	Use whole milk, cream, or plant-based milk
Cheese (optional)	1 cup shredded	Cheddar, mozzarella, or Monterey Jack
Breadcrumbs (optional)	½ cup	For a crunchy topping

Using fresh squash and spinach gives this spinach and squash recipe a brighter flavor compared to canned or frozen substitutes.

The freshness of the produce is what makes this casserole shine. Squash provides a mild, creamy base, spinach layers in leafy green goodness, and corn pops with slight sweetness in every bite. When baked together, they create a balance that’s comforting yet nourishing.

Step-by-Step Method to Bake the Perfect Spinach and Squash Casserole with Corn

Prep the oven and dish – Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with olive oil or butter.
Sauté the vegetables – Warm olive oil in a skillet over medium heat. Cook onion until translucent, stir in garlic, then add squash for 5 minutes until tender. Add spinach last and wilt briefly.
Mix the base – In a bowl, whisk eggs and milk or cream. Season with salt, pepper, and herbs. Add half the cheese if desired.
Layer the casserole – Spread the vegetable mix in the dish, sprinkle corn kernels, then pour in the egg mixture to coat everything.
Top it off – Add remaining cheese and breadcrumbs if using.
Bake until golden – Cook uncovered 30–35 minutes until set and browned. Rest 5 minutes before serving.

The result is a bubbling, beautiful corn and squash casserole that slices cleanly and serves a crowd. Layering ensures every bite has the perfect trio of flavors: sweet, creamy, and garden-fresh.
