Ingredients
- Broccoli florets – From about 1 large broccoli crown, or you can use frozen broccoli chunks.
- Sharp cheddar cheese – Or use your favorite cheese blend.
- Cream of mushroom soup – You can also use cream of chicken soup, cream of celery, or whatever you have on hand.
Instructions
- Preheat the oven to 375°F and lightly grease an 8×8-inch baking dish with butter or non-stick cooking spray.
- Steam the broccoli until just tender but still vibrant green (about 5–7 minutes). If using frozen broccoli, cook according to package directions and drain well.
- Mix the broccoli, shredded cheddar, and cream of mushroom soup in a large bowl until well combined.
- Transfer the mixture to the prepared baking dish and spread it evenly.
- Bake for 20–25 minutes until bubbly and hot. For a golden top, broil for the last 2–3 minutes, watching closely.
- Cool for 5 minutes before serving. Enjoy warm on its own or as a comforting side.
Step by Step Process
Chef Jenn’s Tips
- For extra flavor, stir in a pinch of garlic powder or black pepper.
- Shred your own cheese for the smoothest melt—pre-shredded can melt kind of gritty because of the anti-caking agents they mix in with the cheese.
- Make it ahead: assemble earlier in the day and bake just before dinner.
- Want a crunch? Add a crushed cracker or breadcrumb topping before baking.
