Getting this casserole just right starts with a handful of simple, fresh ingredients that work together beautifully. Each element adds something important—texture, flavor, or richness—making the final dish a heartwarming treat.

Yellow squash (2 pounds, sliced): The star of the dish, providing a tender, slightly sweet base.
Sweet onion (½ large, thinly sliced): Adds a mellow balance and subtle sweetness.
Salt (1 teaspoon, divided): Enhances the flavors and seasons each component perfectly.
Large egg (1): Acts as a binder to keep everything creamy and cohesive.
Mayonnaise (½ cup): Brings richness and moisture without overwhelming the squash.
Sharp cheddar cheese (½ cup): Adds a tangy depth and melty goodness.
Black pepper (¼ teaspoon): Gives a subtle kick that lifts the flavors.
Buttery crackers (½ cup, crushed): Creates that irresistible crunchy topping.
Fresh parsley (for garnish): A vibrant finishing touch that brightens the dish.

How to Make Trisha Yearwood Squash Casserole Recipe

Step 1: Prepare and Cook the Vegetables

Start by placing the sliced yellow squash and thinly sliced sweet onion into a saucepan. Add enough water to just cover the veggies and stir in half a teaspoon of salt. Cover the pot and cook this gently for 10 to 15 minutes, until the squash and onion become tender but not mushy. Then, drain the water thoroughly to avoid any sogginess later.

Step 2: Combine the Casserole Ingredients

Transfer the cooked squash and onion to a large mixing bowl. Add the mayonnaise, egg, sharp cheddar cheese, remaining salt, and black pepper. The egg and mayo will add creaminess and help hold the mixture together while the cheddar amps up the flavor. Mix everything well so all those wonderful ingredients blend into a smooth, rich filling.

Step 3: Assemble the Casserole

Grease a 2-quart casserole dish, ideally an 8×8 inch, to prevent sticking. Spread the squash mixture evenly inside the dish. Then, sprinkle the roughly crushed buttery crackers over the top, creating that much-loved crunchy crust that makes this casserole so special.

Step 4: Bake Until Golden and Bubbly

Preheat your oven to 350°F. Bake the casserole for 25 to 30 minutes, or until it begins to bubble around the edges and the cracker topping turns a gorgeous golden brown. Once done, allow it to cool for a couple of minutes before garnishing and serving.

Step 5: Final Touch and Serve

Before serving, sprinkle chopped fresh parsley over the casserole. This adds a pop of color and fresh aroma, instantly lifting the dish from simply delicious to a showstopper.

Garnishes

While parsley is a classic garnish here, you can also experiment with a little extra shredded cheddar sprinkled on top before baking or add a scattering of crispy bacon bits for a smoky twist. A light drizzle of hot sauce right before serving gives it a little zing that guests will love.

Side Dishes

This casserole pairs wonderfully with grilled or roasted meats like chicken, pork chops, or brisket. For a vegetarian pairing, a fresh green salad or a plate of roasted root vegetables complements the creamy squash beautifully. It’s equally perfect alongside a hearty bowl of soup to warm you up on cooler days.

Creative Ways to Present

For a party or potluck, consider baking the casserole in individual ramekins for personal servings that look both charming and elegant. Alternatively, you can transform leftovers into a layered gratin with fresh slices of tomato or add some cooked quinoa or rice beneath the squash layer for a filling casserole dinner mash-up.

Make Ahead and Storage

Storing Leftovers

Once cooled, cover any leftover squash casserole tightly with plastic wrap or transfer to an airtight container and refrigerate. It stays good for up to 3-4 days, making it ideal for easy weekday meals.

Freezing

You can freeze this casserole for longer storage. Make sure to cool it completely, then wrap it well in foil and plastic wrap or place it in a freezer-safe container. It keeps its quality for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator before reheating.

Reheating

Reheat leftovers gently in the oven at 325°F until warmed through to keep the topping crisp. Alternatively, a microwave works too, but the crunch can soften. Finish with a quick broil if you want to revive the golden cracker crust.

FAQs

Can I use a different type of squash for this casserole?

Absolutely! Yellow squash is traditional in the Trisha Yearwood Squash Casserole Recipe, but zucchini or a mix of summer squashes will work well too. Just be sure to slice them similarly and adjust cooking time if needed.

Is mayonnaise necessary in this recipe?

Mayonnaise is key for creating that creamy texture and rich flavor that makes this casserole shine. If you want a lighter version, you could try substituting with Greek yogurt, though the flavor and texture will be slightly different.

Can I make this casserole vegetarian or vegan?

The recipe is vegetarian-friendly as is but not vegan due to eggs, cheese, and mayonnaise. For a vegan adaptation, try using vegan mayo and cheese substitutes, along with a flax egg or another egg replacer, although the texture might vary.

Do I need to peel the squash?

There’s no need to peel the squash; the skin is tender and adds color and nutrients to the casserole. Just be sure to wash the squash thoroughly before slicing.

What type of crackers work best for the topping?

Buttery, flaky crackers like Ritz are perfect for the topping in the Trisha Yearwood Squash Casserole Recipe. They give a lovely buttery crunch and golden finish, but you can experiment with saltines or herb-flavored crackers for a twist.
