Key Ingredients & Substitutions
Yellow Squash: This is the star of the dish! You can easily substitute zucchini if that’s what you have on hand. Both have a similar texture when baked.
Onion: A sweet or yellow onion works best for this recipe. If you need a milder flavor, consider using green onions or shallots instead.
Cheddar Cheese: While I love sharp cheddar for its bold flavor, you can swap in mozzarella or Monterey Jack for a creamier taste. Vegan cheese can also be used for a dairy-free option.
Sour Cream: If you’re out, Greek yogurt is a great substitute that adds a similar creaminess. You can also use dairy-free yogurt if necessary.
Mayonnaise: You could replace this with more sour cream or Greek yogurt for a lighter version. A vegan mayo is also available for those who want to keep it plant-based.
How Do I Blanch Squash Without Making It Mushy?
Blanching is key to keeping your squash firm and flavorful. Here’s how to do it right:
- Bring a sizable pot of salted water to a rolling boil.
- Drop in your sliced yellow squash and chopped onion. Boil for about 5 minutes.
- Drain immediately and rinse with cold water to stop the cooking process.
- Pat dry with paper towels to soak up excess moisture – this helps the casserole not get soggy!
Taking these steps ensures your squash retains its texture and doesn’t become mushy in the casserole. Happy cooking!
