Summer Squash Casserole Ingredients

Below is a concise overview of the ingredients and basic steps. Full ingredient quantities and detailed directions are shown in the recipe card further down the page. Tip: chop your vegetables the night before to save time.

• Sliced fresh squash: a mix of yellow bottleneck squash and zucchini, ripe and unblemished.
• Diced sweet bell peppers: red, yellow, or green add color and sweetness.
• Chopped onion: Vidalia is great for a mellow, sweet flavor, but white or yellow work fine.
• Sliced celery: slice thin for picky eaters if needed.
• Minced garlic: fresh or jarred.
• Shredded cheese: pepper jack for a little heat or white cheddar for a milder option.
• Canned cream soup: cream of celery or chicken for the sauce base.
• Seasonings: salt and ground black pepper to taste.
• Boxed stuffing mix: savory herb stuffing adds seasoning and texture; choose another flavor if preferred but adjust seasonings accordingly.
• Unsalted butter: used to moisten and fluff the stuffing topping.

📌Pro Recipe Tip

Prep the vegetables the night before—slice, chop, and mince ahead to shorten active cook time.

Directions

Step 1: Layer sliced yellow squash and zucchini in the bottom of an 8-quart crock pot, cutting larger pieces in half for even cooking.

Step 2: Add diced bell pepper, chopped onion, sliced celery, and minced garlic on top of the squash.

Step 3: Use a large spoon to toss the vegetables gently so they are evenly distributed.

📌Pro Slow Cooking Tip

Layering and then stirring helps ensure the ingredients are evenly combined in the crock pot.

Step 4: Melt ½ cup butter, stir in the stuffing mix, and fluff with a fork. Remove one cup of the mixture and set it aside to use as a crunchy topping later.

Step 5: Add the canned cream soup, shredded cheese, salt, and pepper to the crock pot. Stir thoroughly to combine the sauce, cheese, and vegetables.

Step 6: Add the remaining stuffing mixture (except the reserved cup) and mix well so the stuffing is distributed throughout the casserole.

Step 7: Cover and slow cook on high for 3 hours or low for 4–5 hours, until the squash and zucchini are tender but still hold their shape.

📌Pro Squash Casserole Tip

The casserole is ready when the squash is tender but not mushy—firm enough to keep its shape.

Squash Casserole Topping

Step 8: Sprinkle the reserved cup of stuffing mix over the top just before serving for crunch. Serve directly from the slow cooker, or transfer to a baking dish for a nicer presentation.

This crock pot summer squash casserole is a convenient, nutritious way to enjoy peak-season squash. The combination of herbs, cheese, and a crunchy stuffing topping makes a satisfying side that complements grilled proteins or stands on its own as a comforting vegetarian option.

Using the slow cooker keeps your kitchen cool and frees you from oven time while still producing a deliciously tender casserole.

Recipe FAQs

📌Pro Slow Cooker Tip

• Slice vegetables evenly so they cook at the same rate.

• Toss vegetables together before adding thick soup to make mixing easier.
• Use a wide casserole-style slow cooker to improve cooking speed and evenness.
• Stir once halfway through the cooking time to promote even doneness.
• For a crunchier topping, brown the reserved stuffing cup in a skillet over medium heat before sprinkling it on top.
