- Lightly grease the inside of your slow cooker.
- In a large bowl, combine soup, sour cream, 1 1/2 cups cheese, garlic powder, salt, and pepper. Stir in broccoli until coated.
- Transfer mixture to the slow cooker and spread evenly.
- In a small bowl, mix cracker crumbs with melted butter. Sprinkle over the top.
- Cover and cook on low for 3–4 hours, or until broccoli is tender and the casserole is heated through.
- Sprinkle remaining cheese on top during the last 10 minutes of cooking, letting it melt before serving.
Note: This casserole is just as good the next day—if you’re lucky enough to have leftovers. Try pairing it with roast chicken, baked ham, or even a simple green salad for a complete comfort meal. And if you want to make it extra special, swap the cheddar for a sharp white cheddar or add a sprinkle of Parmesan to the topping before serving.
