Cheesy Slow Cooker Cauliflower Casserole

Sometimes, the simplest dishes bring the most comfort, especially when they simmer away quietly, filling the kitchen with inviting aromas. This cheesy slow cooker cauliflower casserole is one of those humble, heartwarming meals that feels like a hug in a bowl.

Ingredients

• A medium head of cauliflower, cut into florets
• A couple of cups of shredded cheddar cheese
• A splash of heavy cream
• A tablespoon of butter
• A pinch of salt and pepper
• A sprinkle of garlic powder for that little extra kick

Instructions

1. Start by greasing the inside of your slow cooker with the tablespoon of butter to prevent sticking.
2. Toss in the cauliflower florets, spreading them out evenly at the bottom.
3. Pour the heavy cream over the cauliflower, just enough to coat them lightly.
4. Season with a pinch of salt, pepper, and that sprinkle of garlic powder, mixing gently to ensure even flavor.
5. Cover the cauliflower with the shredded cheddar cheese, creating a generous, even layer.
6. Set your slow cooker to low and let it work its magic for about 4 hours, or until the cauliflower is tender and the cheese is bubbly and golden.
7. Tip: Resist the urge to stir too often; letting it be ensures the cheese melts perfectly over the cauliflower.
