Ingredients and Their Roles
- 4 cups broccoli florets – The heart of the dish, broccoli provides a tender-yet-slightly-crisp texture and a fresh, earthy flavor that balances the richness of the cheese sauce.
- 2 cups shredded cheddar cheese – Sharp cheddar melts beautifully and delivers that classic, bold cheese flavor everyone expects from a broccoli casserole.
- 1 cup milk – Milk forms the base of the sauce, helping to create a smooth and creamy consistency without being overly heavy.
- 1/2 cup heavy cream – This adds luxurious richness and body to the cheese sauce, making every bite indulgent.
- 1/4 cup grated Parmesan cheese – Parmesan contributes a nutty, salty depth and helps form a golden crust when broiled.
- 1/4 cup breadcrumbs – Breadcrumbs provide a crisp contrast to the creamy casserole, elevating the overall texture.
- 1/4 cup chopped fresh parsley – Parsley adds a fresh, herbaceous finish and brightens the dish visually and flavor-wise.
- 1/4 cup chopped green onions – Mildly sharp and fresh, green onions cut through the richness and add complexity.
- 2 tablespoons unsalted butter – Butter enriches the sauce and ensures a silky mouthfeel.
- 1 teaspoon garlic powder – Garlic powder provides subtle savory depth without overpowering the cheese.
- Salt and pepper to taste – Essential for balancing and enhancing all the flavors in the casserole.
Step-by-Step Instructions
- Prepare the slow cooker: Lightly grease the inside of your slow cooker with butter or non-stick spray. This prevents sticking and makes cleanup effortless.
- Add the broccoli: Place the broccoli florets evenly in the slow cooker, ensuring consistent cooking throughout.
- Create the cheese sauce: In a medium saucepan over medium heat, melt the butter. Stir in the milk, heavy cream, and garlic powder. Heat gently until warm, being careful not to boil.
- Melt the cheese: Gradually add the shredded cheddar cheese, stirring constantly until the sauce is smooth and fully melted. Season with salt and pepper.
- Combine and cook: Pour the cheese sauce over the broccoli and gently stir to coat. Cover and cook on low for 3–4 hours, until the broccoli is tender but not mushy.
- Prepare the topping: Preheat your oven’s broiler. Transfer the broccoli mixture to an oven-safe dish.
- Broil to perfection: Sprinkle Parmesan cheese and breadcrumbs evenly over the top. Broil for 3–5 minutes until the topping is golden brown and crisp.
- Garnish and serve: Finish with chopped parsley and green onions just before serving.

- Make it gluten-free: Substitute breadcrumbs with crushed gluten-free crackers or omit them entirely.
