Equipment
Ingredients
- 5 cups broccoli florets fresh or frozen
- 1 cup heavy whipping cream
- 2½ cups shredded cheddar cheese divided
- salt and pepper to taste
Instructions
- Preheat & Prep the Dish: Preheat your oven to 400°F. Spray eight 4-ounce ramekins or a 9×13-inch glass baking dish with non-stick spray. Place ramekins on a baking tray if using. Set aside.
- Prep the Broccoli: If using fresh broccoli, wash thoroughly, trim off the stems, and chop into bite-sized florets. If using frozen broccoli, thaw completely and pat dry to remove excess water.
- Soften the Broccoli: Place 5cups broccoli florets in a large microwave-safe bowl. Cover with plastic wrap and microwave for 3–4 minutes, until just tender but still crisp. Carefully remove the plastic wrap.
- Season & Mix: Season the broccoli with salt and pepper to taste. Pour in 1 cup heavy whipping cream and stir in 1 ½ cups of the shredded cheddar cheese, tossing everything together until the broccoli is well coated.
- Assemble the Bake: Divide the broccoli mixture evenly among the ramekins, filling them to the top edge. If using a 9×13 dish, spread the mixture evenly across the bottom, ensuring it’s level.
- Top with Cheese: Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top of each ramekin (or across the casserole if using a baking dish).
- Bake: Bake in the preheated oven for 13–17 minutes, or until the cheese is fully melted and golden brown on top.
- Serve: Let cool for a couple of minutes, then serve warm and enjoy!

Recipe Tips
- Don’t Use Wet Broccoli: Whether you’re using fresh or frozen broccoli, make sure it’s not too wet when it goes into the mix. If you’re using fresh, give it a good shake after washing. For frozen, let it thaw with a sprinkle of salt and then pat down with a paper towel. This helps avoid any unwanted sogginess in your broccoli cheese casserole.
- Block Cheese Is Best: For the best melt and flavor, stay away from pre-shredded cheese. It might take an extra minute, but shredding your own cheese right off the block ensures a smoother melt and a fresher taste.
- Distribute the Mix Evenly: When you’re distributing the broccoli mixture into the casserole, aim for an even spread. This helps every bite cook uniformly.
- Watch that Casserole: Keep a close eye on your broccoli cheese casserole in those last few minutes of baking. You’re looking for that perfect golden brown on top. It’s the sweet spot!

You’re 100% right that this did not look like anything amazing… but, like you said, it was easy to make and tasted good. Thanks!
You’re so welcome!
I made this to go along with some baked chicken and it turned out great! I did add the suggested bacon bits on top and I almost forgot I was eating broccoli.
Yess! I love it with bacon bits on top and sometimes I’ll add some Greek yogurt for like a mock potato (but, I mean nothing really can replace a good ol baked potato)
