- 1 tsp. minced garlic
- 1 tsp. salt
- 1/2 tsp. ground black pepper
- 1/2 tsp. dried thyme
- 1 tbsp. fresh parsley – chopped
Equipment Needed

- Colander – for draining the vegetables
- Cutting board and knife – for chopping vegetables
- Measuring cups and spoons
- Mixing spoon
Preparation Instructions
Step 1: Prepare the Cornbread
Prepare the Jiffy corn muffin mix according to package directions. Bake, then cool completely before crumbling for the topping. This cornbread base is essential for achieving the signature texture of the Boston Market version.
Step 2: Cook the Squash
Combine the diced zucchini and yellow squash in a large saucepan. Add just enough water to cover the vegetables. Cook over medium-low heat until tender, then remove from heat. Drain, reserving one cup of the cooking liquid for later use in the casserole.
Step 3: Sauté the Aromatics
In a separate large pan, melt the butter over medium-low heat. Add the chopped onions and sauté until translucent. While the onions cook, add the salt, black pepper, dried thyme, and fresh parsley for seasoning. Next, stir in the chicken bouillon cubes and minced garlic, ensuring everything is well combined.
Step 4: Combine Ingredients
Add the drained squash and zucchini to the onion mixture. Stir in the diced cheese until it begins to melt into the vegetables. Gently crumble the prepared cornbread into the pan, then pour in the reserved cup of cooking liquid. Mix everything together thoroughly to ensure an even distribution of flavors and textures.
Step 5: Bake the Casserole
Transfer the mixture to a greased 9×13-inch baking dish. Cover with foil to prevent excessive browning and bake in a preheated 350°F oven for 40–50 minutes. Remove the foil for the last 20 minutes of baking to allow the top to become golden and slightly crisp.
Serving Suggestions
This squash casserole pairs well with a variety of main dishes. Consider serving it alongside:
- Grilled chicken – adds smoky flavor and protein.
- Roasted turkey or ham – perfect for holiday meals.
- Garlic bread – offers a crunchy contrast to the creamy casserole.
- Mixed green salad – provides a fresh, light balance.
For extra flair, top servings with a dollop of sour cream, crispy bacon crumbles, pickled jalapeños, or a drizzle of honey for a sweet-savory twist.
Variations and Substitutions
Vegetarian/Vegan Options
To make this recipe vegetarian, substitute the chicken bouillon cubes with vegetable bouillon. For a vegan version, use dairy-free butter and cheese.
Cheese Choices
While American and Cheddar cheeses are traditional, feel free to experiment with Monterey Jack, Colby, or even a blend of cheeses for a richer flavor profile.
Alternative Toppings
If you prefer a different topping, try crushed crackers, panko breadcrumbs, or a layer of herbed stuffing mix for added crunch.
Tips for Success
- Prepare in Advance: Assemble the casserole up to a day ahead and refrigerate. Bake just before serving to save time.
- Fresh Herbs: Use fresh parsley and thyme for the best flavor, though dried herbs can be substituted if needed.
- Vegetable Texture: Don’t overcook the squash; it should be tender but not mushy.
- Moisture Control: Reserve the cooking liquid for the right casserole consistency, but don’t add too much or the dish can become soggy.
