Did you know that summer squash casserole has been a Southern church potluck staple since the 1950s — and that the buttery Ritz cracker topping is what consistently earns it “best dish” honors? Summer squash casserole with Ritz crackers turns a glut of yellow garden squash into a creamy cheesy comforting bake topped with golden buttery cracker crumbs. Fifty minutes from cold pantry to a 9×13 casserole that disappears at every potluck.
Ingredients List
Vegetables: 2 lbs yellow summer squash (4-5 medium) sliced into 1/4-inch rounds + 1 large Vidalia or yellow onion thinly sliced + 3 tbsp butter + 1/2 tsp salt
Cream sauce: 1 can (10.5 oz) cream of chicken soup + 1 cup sour cream + 1 1/2 cups shredded sharp cheddar + 1/2 cup grated parmesan + 1 tsp garlic powder + 1 tsp dried thyme + 1/2 tsp salt + 1/4 tsp black pepper + 2 large eggs lightly beaten
For garnish: Fresh chives + parsley + cracked pepper
Timing
Sauté squash: 10 min. Mix + assemble: 10 min. Bake: 25 min. Rest: 5 min. Total: 50 minutes.
Step 1 — Sauté Squash and Onion
Melt butter in a large skillet over medium-high. Add squash and onion; cook 8-10 min, stirring, until softened and slightly golden. Squeeze out excess water with a clean towel (squash is watery — this prevents soggy casserole). Season with salt.
Step 2 — Mix the Cream Sauce
In a large bowl, whisk cream of chicken soup, sour cream, cheddar, parmesan, garlic powder, thyme, salt, pepper, and eggs until smooth.
Step 3 — Combine With Squash
Fold sautéed squash + onion into the cream sauce until evenly coated. Transfer to a greased 9×13 baking dish; smooth top.
Step 4 — Make the Ritz Topping
In a separate bowl, combine crushed Ritz crackers, melted butter, cheddar, and parsley. Mix until crumbs are evenly coated.
Step 5 — Top the Casserole
Sprinkle Ritz mixture evenly across the top of the casserole, covering completely. Press lightly to adhere.
Step 6 — Bake and Rest
Preheat oven to 350°F. Bake 22-25 min until topping is deeply golden brown and edges are bubbling. Rest 5 min — sauce sets. Garnish with chives, parsley, cracked pepper. Serve hot.
