My grandmother used to make this every single Sunday after church, and the smell alone would have us kids practically climbing the walls waiting for dinner. I swear, the second that buttery, cheesy aroma hit the kitchen, we knew it was going to be a good day.
This squash casserole is the kind of thing that doesn’t look fancy, but somehow it’s always the first dish to disappear at potlucks. Creamy yellow squash baked until tender, folded into sharp cheddar and sweet caramelized onions, then topped with golden buttery breadcrumbs that get crispy and toasted on top. It’s comfort food that tastes like home.
The best part? It’s so simple. You don’t need fancy ingredients or complicated techniques. Just fresh squash, a little love, and about 45 minutes in the oven.
**INGREDIENTS:**
• 4 cups yellow squash, sliced into rounds
• 1 onion, chopped
• 2 cloves garlic, minced
• 1 cup shredded sharp cheddar cheese
• ½ cup sour cream
• 2 eggs, beaten
• 1 cup breadcrumbs (or crushed Ritz crackers for extra richness)
• 3 tablespoons butter, melted
• Salt and black pepper to taste
• Fresh parsley for garnish
**INSTRUCTIONS:**
Preheat your oven to 350°F and lightly grease a 9×13 baking dish.
Bring a pot of salted water to a boil and add the sliced squash. Cook for about 5–7 minutes until tender but not mushy. Drain well and gently press out any extra water.
In a skillet, sauté the chopped onion and garlic in a little butter until soft and golden, about 4 minutes.
In a large bowl, combine the cooked squash, sautéed onion and garlic, shredded cheddar, sour cream, and beaten eggs. Season generously with salt and pepper. Mix gently until everything is coated and creamy.
Pour the squash mixture into your prepared baking dish and spread it out evenly.
In a small bowl, toss the breadcrumbs with the melted butter until they’re coated. Sprinkle this evenly over the top of the casserole.
Bake for 30–35 minutes, until the top is golden brown and crispy, and the edges are bubbling.
Let it cool for just a few minutes, then garnish with fresh parsley.
Serve this warm alongside roasted chicken, grilled pork chops, or honestly just eat it straight from the dish with a spoon. No judgment here.
Would you add extra cheese or keep it traditional?
