Servings: 6

Course: Side Dish

Cuisine: American

Ingredients Method

Ingredients

  

• 4 c. cauliflower florets chopped into bite-sized pieces
• 6 oz. cream cheese cut into chunks
• ¼ c. heavy cream
• 3 T. unsalted butter softened
• ¼ t. garlic powder
• ½ t. dried dill
• Sea salt and black pepper to taste
• 1½ c. Italian cheese blend shredded
• 4 strips bacon cooked and crumbled
• 1 T. fresh chives chopped

Method

 

1. Preheat oven to 400°F with rack in center position.
2. Place the cauliflower in a steamer basket over boiling water. Steam until just fork-tender, about 6–7 minutes.
3. Transfer the cauliflower to a colander and let it drain for a minute or two. Pat very dry with paper towels to remove as much excess moisture as possible.
4. Add the cauliflower to a large bowl with the cream cheese, heavy cream, butter, garlic powder, and dried dill. Season with salt and pepper and toss gently to combine.
5. Transfer to oven-safe casserole dish. Top with shredded Italian cheese blend and crumbled bacon.
6. Bake 8-10 minutes until cheese is melted and nicely browned on top.
7. Remove from oven and top with fresh chives. Serve immediately.

For best results:

• Steam cauliflower until just fork-tender, not mushy
• Pat cauliflower very dry before mixing with sauce
• Use softened cream cheese. It melts faster into the hot cauliflower
• Cook the bacon until it’s crispy for the best texture

Shop This Recipe

To make this Loaded Cauliflower Au Gratin, you’ll need:

• 2-quart casserole dish — just the right size for this gratin, and pretty enough to go straight from the oven to the table.
• Steamer basket — cooks the cauliflower until tender without waterlogging it.
• Box grater — freshly shredded cheese melts beautifully and takes about two minutes more than opening a bag.

• 3-piece Staub baking dish set — a basic 2-quart casserole dish works perfectly here, but this is a beautiful upgrade if you want oven-to-table bakeware you’ll use for gratins, casseroles, roasted vegetables, and holiday sides for years.

Variations:

• Extra loaded: Add sour cream or ranch dressing
• Spicy: Include jalapeños or red pepper flakes
• Herbier: Use fresh dill instead of dried. Thyme or rosemary are also great choices.
• Vegetarian: Skip the bacon, add extra cheese

Cheese options:

• Italian blend = mozzarella, parmesan, provolone mix
• Make your own blend with your favorite cheeses or what you have on hand.
• Sharp cheddar works great
• Consider Gruyere for a fancy upgrade
• Add parmesan for extra flavor

Frequently Asked Questions

Q: Can I use frozen cauliflower?
A: Yes! Steam from frozen, just add 2-3 minutes to cooking time.

Q: My cauliflower is watery. What happened?
A: It didn’t get drained well enough after steaming. Drain it and pat very dry.

Q: Can I make this ahead?
A: Sure. Assemble it without the shredded cheese & bacon, and refrigerate up to 1 day. Add your toppings when you’re ready to bake.

Q: How do I reheat leftovers?
A: 350°F oven for 10 minutes, or microwave until hot.
