Preparing Squash Casserole

Ingredients Overview

For a basic squash casserole, you’ll need:

  • Yellow squash (fresh or frozen)
  • Chopped onions
  • Grated cheddar cheese
  • Eggs
  • Ritz crackers (or a gluten-free alternative)
  • Butter
  • Seasonings (salt, pepper, optional cayenne)

Step-by-Step Recipe

  1. Prepare the Squash: Slice the yellow squash thinly and chop the onions. Sauté them together in butter until they are soft.
  2. Mix the Ingredients: In a large bowl, whisk together the eggs, cheese, and seasonings. Add the cooked squash and onions to this mixture, stirring until well combined.
  3. Bake the Casserole: Preheat your oven to 350°F. Pour the mixture into a greased casserole dish. Top with crushed Ritz crackers. Bake for 45 minutes or until the topping is golden brown.
  4. Serve: Let the casserole sit for a few minutes before serving to allow it to set.

Recipe Variations

If you’re looking to mix things up, try these variations:

  • Gluten-Free: Swap out Ritz crackers for gluten-free crackers or breadcrumbs.
  • Additional Flavors: Add herbs like thyme or rosemary for extra flavor, or incorporate vegetables like zucchini for a twist.

Common Mistakes to Avoid

  • Overcooking the Squash: Make sure the squash is tender but not mushy.
  • Bland Flavors: Don’t skimp on seasonings. Balance the salt, pepper, and optional cayenne pepper to taste.
  • Burning the Topping: Keep an eye on the oven to ensure the topping doesn’t burn while the casserole bakes.

Tips for the Best Squash Casserole

Choosing the Right Squash

When selecting squash, go for firm, blemish-free squash with a vibrant yellow color. Avoid squash that feels soft or has wrinkled skin. If fresh squash is out of season, frozen squash is a great alternative.

Make-Ahead and Freezing Tips

Squash casserole can be easily prepared in advance:

  • Make-Ahead: Assemble the casserole without baking, cover it tightly, and refrigerate for up to 24 hours.
  • Freezing: Prepare the casserole but leave off the cracker topping. Freeze the uncooked casserole for up to 3 months. When ready to serve, thaw it overnight in the fridge, top with crackers, and bake as usual.
