Ingredients You’ll Need

Every ingredient in this Slow-Cooker Broccoli Casserole Recipe plays a key role — from the sharp cheddar that adds rich tang, to the cream of celery soup that’s the magic glue binding it all together. Shopping for these is straightforward, and you probably have most of them in your pantry already.

• Frozen chopped broccoli: Using frozen saves time and keeps the broccoli tender but not overcooked.
• Condensed cream of celery soup: This brings depth and creaminess; feel free to swap with cream of mushroom or chicken if you like.
• Sharp cheddar cheese: I love the tangy bite sharp cheddar gives, but you can mix cheeses for a milder taste.
• Chopped onion: Adds a subtle sweetness and texture — don’t skip this!
• Worcestershire sauce: A secret trick I discovered adds umami richness without overpowering.
• Pepper: Simple seasoning to balance flavors.
• Crushed butter-flavored crackers: These create the perfect buttery, crunchy topping that makes this dish irresistible.
• Butter: Dotting on top ensures a golden, melty crust after slow cooking.

Variations

I like to experiment with this Slow-Cooker Broccoli Casserole Recipe, especially when I want to cater it for different occasions or preferences. The beauty is you can easily personalize it without losing the comforting essence.

• Make it vegetarian: Swap out Worcestershire sauce for a vegetarian version or use soy sauce for a different umami kick—I did this for a friend once and it worked wonders!
• Cheese swap: Use gouda or gruyere for a nuttier flavor; I’ve found mixing cheeses gives a fun twist.
• Add protein: Stir in cooked chicken or bacon bits before slow cooking to make it a more substantial meal.
• Spice it up: A pinch of cayenne or smoked paprika adds warmth if you’re feeling adventurous.

How to Make Slow-Cooker Broccoli Casserole Recipe

Step 1: Mix Your Ingredients

Start by tossing your partially thawed broccoli with the undiluted cream of celery soup, 1 cup of shredded sharp cheddar, chopped onion, Worcestershire sauce, and pepper in a large bowl. I find that mixing everything well at this stage ensures every bite is packed with flavor. If the broccoli feels very icy, just let it sit to thaw a bit more—too much frozen moisture can make the casserole watery.

Step 2: Layer into the Slow Cooker

Grease your 3-quart slow cooker to prevent sticking, then pour in the broccoli mixture evenly. Next, sprinkle the crushed butter-flavored crackers on top and dot them generously with butter. This buttery topping browns beautifully during the cook and gives a lovely texture contrast to the creamy base.

Step 3: Slow Cook to Perfection

Cover and cook on high for about 2 ½ to 3 hours. You’ll want to check toward the end—the broccoli should be tender but not mushy, and the flavors will have melded perfectly. Finally, sprinkle the remaining ½ cup of cheddar cheese on top and cook for an additional 10 minutes so it melts into a luscious finish. I love this little step—it makes the dish extra cheesy and irresistible.

How to Serve Slow-Cooker Broccoli Casserole Recipe

Garnishes

I love adding a sprinkle of fresh chopped parsley or green onions on top just before serving—it adds a fresh pop of color and a bit of brightness against all that creamy, cheesy goodness. Sometimes, a little extra cracked black pepper finishes it off nicely too.

Side Dishes

This Slow-Cooker Broccoli Casserole makes a great side to roasted chicken, baked ham, or even hearty burgers. Pair it with some garlic mashed potatoes or a simple mixed green salad to round out your meal with ease.

Creative Ways to Present

For a festive dinner, I’ve served this casserole in individual ramekins topped with a little extra cracker crumb and cheese, then broiled briefly for a golden crust. It makes guests feel special and plated casseroles keep warm nicely on a buffet table.

Make Ahead and Storage

Storing Leftovers

After it cools, I transfer leftovers to an airtight container and keep them in the fridge for up to 3 days. The casserole holds up well and reheats nicely, maintaining its creamy texture without drying out.

Freezing

I’ve frozen this casserole successfully by letting it cool completely, portioning it into freezer-safe containers, and reheating slowly in the oven. The texture stays pretty good—it’s a fantastic make-ahead meal when you prep extras.

Reheating

To reheat, I prefer warming it in the oven at 350°F covered with foil to prevent drying out. If you’re in a hurry, microwaving works too—just stir halfway through to heat evenly.
