• ½ cup grated Parmesan cheese
• ½ cup sour cream or Greek yogurt
• ½ cup breadcrumbs

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray.

Step 2: Prepare the Squash

Slice the yellow squash and set aside. In a large skillet, melt the butter over medium heat. Add the onion and garlic, sautéing until fragrant and soft, about 3–4 minutes.

Step 3: Make the Cheese Sauce

In a small bowl, whisk together milk and flour until smooth. Pour the mixture into the skillet with the onions and garlic. Cook, stirring constantly, until it thickens slightly. Remove from heat and stir in cheddar cheese, Parmesan, and sour cream until creamy and smooth.

Step 4: Combine Squash and Cheese

Add the sliced squash to the skillet and toss to coat evenly with the cheese sauce. Season with salt, pepper, and paprika if using.

Step 5: Transfer to Baking Dish

Pour the cheesy squash mixture into the prepared baking dish. Sprinkle breadcrumbs evenly over the top. For extra cheesy goodness, add a little more shredded cheese on top.

Step 6: Bake Until Golden

Bake in the preheated oven for 25–30 minutes, or until the top is golden brown and the casserole is bubbly. Remove from the oven and let it cool slightly before serving.
