Key Ingredients & Substitutions
Yellow Squash: You’ll need about 4 medium yellow squashes. If you can’t find yellow squash, zucchini can be a great substitute. Both have a mild flavor and work well in this dish.
Sour Cream: I love using sour cream for its creamy texture. If you’re looking for a lighter option, Greek yogurt can replace the sour cream while keeping that creamy goodness.
Cheddar Cheese: Sharp cheddar adds a nice tangy flavor. If you prefer, you could use Monterey Jack or Pepper Jack for a little heat, or even a non-dairy cheese if needed.
Creamy Crackers: I usually use Ritz crackers for that buttery crunch. If you’re gluten-free, try using gluten-free crackers or panko breadcrumbs for a similar texture.
How Do You Cook the Squash Just Right?
The cooking method for the squash is key to this recipe. Boiling it helps soften the squash quickly without losing its texture. Here’s a quick guide:
- Bring a large pot of salted water to a boil.
- Add the sliced squash and chopped onion, boiling for about 5 minutes.
- Drain the vegetables well—this keeps your casserole from becoming watery.
After draining, let them cool slightly before mixing them into the other ingredients. This tip works best to achieve that creamy, but not mushy, texture in your casserole!
