  • Total Time: 45 minutes
  • Yield: 6 servings

Ingredients

Vegetables

  • 2 1/2 pounds yellow squash, cut into 1/4 inch slices
  • 1 cup white onion, diced
  • 3 cloves garlic, minced

Cheesy Sauce

  • 1/2 cup mayonnaise
  • 1/2 cup sour cream
  • 1/2 cup milk
  • 2 large eggs
  • 1/4 teaspoon cayenne pepper
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 cup parmesan cheese, grated
  • 2 cups Colby Jack cheese, shredded
  • 2 teaspoons fresh thyme or 1/2 teaspoon dried thyme

Cracker Topping

  • 1 sleeve Ritz crackers, crushed
  • 4 tablespoons butter, melted

Instructions

  1. Preheat and prepare dish: Preheat the oven to 350°F (175°C) and spray an 8×8 baking dish with nonstick cooking spray to prevent sticking.
  2. Slice the squash: Cut the yellow squash into 1/4 inch slices, making sure they are not thinner to avoid a mushy texture once cooked.
  3. Sauté squash and onions: Heat a large skillet over medium-high heat, melt 2 tablespoons of butter, then add the sliced squash and diced onion. Cook for about 8 minutes until softened.
  4. Add garlic: Stir in the minced garlic and cook for an additional 30 seconds before removing the skillet from heat.
  5. Drain excess liquid: Transfer the cooked squash mixture to a colander and gently stir to release as much liquid as possible. Let it drain for about 10 minutes.
  6. Prepare cheesy sauce: In a small bowl, whisk together mayonnaise, sour cream, milk, eggs, parmesan cheese, Colby Jack cheese, cayenne pepper, salt, black pepper, and thyme until fully combined.
  7. Make cracker topping: In another small bowl, mix the crushed Ritz crackers with the melted butter until the crackers are well coated.
  8. Assemble casserole: Spread one-third of the cheesy sauce evenly in the bottom of the prepared baking dish. Layer half of the drained squash mixture over the sauce, then add another one-third of the sauce. Add the remaining squash and top with the remaining cheesy sauce.
  9. Add topping and bake: Evenly sprinkle the buttered cracker topping over the assembled casserole. Bake in the preheated oven for 25-30 minutes or until the topping is golden brown and the casserole is cooked through.

Notes

  • Any buttery cracker like Ritz works excellently for the topping.
  • Store leftovers in an airtight container in the refrigerator and consume within 3-4 days for best quality.
