Key Ingredients and Substitutions

  • Fresh Yellow Squash: Use zucchini if you don’t have yellow squash, or even a mix of both for some variety.
  • Shredded Cheddar Cheese: Any melty cheese will work, like Monterey Jack or Colby.
  • Ritz Crackers: Substitute with crushed pretzels, breadcrumbs, or even crushed tortilla chips for a fun twist.
  • Butter: Swap with olive oil or margarine if you’re watching dairy.
  • Onion: For a milder taste, go for shallots. If you’re avoiding onion altogether, scallions work too!

How to Make the Recipe (Step-by-Step)

  • Preheat your oven to 350°F. It’s go-time! Set your oven temperature first to make sure it’s hot at just the right moment.
  • Wash and slice your squash. Slice them into thin, even rounds to encourage quick and consistent cooking.
  • Cook the squash and onion in a skillet. You’ll want to lightly sauté them until they’re softened, which takes about 5-7 minutes.
  • Mix the creamy filling in a big bowl. Combine the cooked squash and onions with shredded cheese, crushed crackers, butter, and any seasonings you enjoy.
  • Pour everything into a greased casserole dish. Spread it evenly so it all bakes properly.
  • Top the casserole with more crackers or cheese. This is where it gets golden and crispy—aka the best part!
  • Pop it in the oven for about 25-30 minutes. Once the top is bubbly and golden brown, it’s ready to serve.

Expert Tips for Success

Use fresh squash when it’s in season for max flavor.
Try salting and draining the squash first if you want to remove extra moisture and avoid a watery casserole.
Don’t skimp on the topping! The crunchy topping gives this dish its signature texture.
Let the casserole sit for 5-10 minutes after baking to set up before serving.
Mix in some garlic powder or paprika to jazz up the flavor—you can’t go wrong!

Variations and Customizations

This casserole is like a blank canvas for your kitchen creativity! Want a healthier version? Swap crackers for whole-wheat breadcrumbs and use reduced-fat cheese. If you’re adding extra veggies, like bell peppers or mushrooms, sauté them first to avoid excess moisture. For meat lovers, try mixing in cooked crumbled bacon or diced ham. And for a spicy kick, toss in some chopped jalapeños or a pinch of red pepper flakes. Whether you’re vegetarian or meat-loving, this recipe easily adapts to your taste buds.

Nutritional Information

Each serving of Mama’s Summer Squash Casserole is approximately 200-220 calories, with about 10 grams of fat, 20 grams of carbohydrates, and 5 grams of protein. It’s a comfort food dish, so it’s not exactly keto, but it provides a good balance of cheesy satisfaction and veggie goodness. If you’re looking to lighten up the recipe, use less cheese and swap regular crackers for a healthier option. Gluten-free eaters can replace the crackers with a gluten-free alternative, too!

Storage and Reheating Instructions

Got leftovers? Lucky you! Store your casserole in an airtight container in the fridge for up to 4 days. For reheating, the oven is your best bet to bring back that crispy topping—bake at 350°F for 10-15 minutes. In a hurry? A microwave works fine, but the topping might not be as crunchy. Pro tip: If freezing, make sure you do so before baking. That way, you can pop it straight from the freezer into the oven when you’re ready to enjoy it again!

Step-by-Step Instructions
 

  • Fire up your oven to a cozy 350°F (175°C), and give your 1-quart casserole dish a good greasing.
  • Introduce a steamer to your saucepan world, adding water just shy of touching the steamer. Boil away! Let the squash and onion relax in there, covered, until perfectly tender and mash-ready, about 10-15 minutes.
  • In the casserole dish, blend egg and sour cream. Join the party by adding squash, onions, 2/3 of the cracker crumbs, and 2/3 of the Cheddar. A quick stir with a fork, and now, finish with the remaining cheese and crackers to create a delightful top layer.
  • Bake away in that preheated oven until the cheese has melted into gooey goodness and the crackers are a lovely golden hue, approximately 30 minutes of culinary bliss.
