Ingredients

3 pounds yellow squash, sliced
1 medium yellow onion, diced
1/4 cup unsalted butter
1/4 cup all-purpose flour
2 cups whole milk
2 cups shredded sharp cheddar cheese
1/2 cup grated Parmesan cheese
Salt and black pepper
1 cup panko breadcrumbs
Fresh parsley for garnish

Instructions

Preheat oven to 375°F and grease a 9x13 inch baking dish.
In a large pot, melt 2 tablespoons of butter over medium heat. Add sliced squash and diced onion; cook until tender-crisp (10-12 minutes). Drain excess liquid.
In the same pot, melt remaining butter and whisk in flour to create a roux. Gradually add whole milk, stirring until smooth and thickened (3-5 minutes).
Remove from heat; stir in 1 1/2 cups cheddar cheese, Parmesan, salt, and pepper until combined.
Fold in cooked squash mixture, pour into baking dish.
Mix remaining cheddar cheese with panko; sprinkle over casserole.
Bake for 25-30 minutes until bubbly and golden brown.
Let rest for 5 minutes before serving; garnish with parsley.

Notes

For added flavor, consider mixing in cooked bacon or using different types of cheese like Gouda or Monterey Jack. You can also substitute zucchini for half of the yellow squash for a unique twist on this classic recipe!
