Creamy Cheesy Cauliflower Bake with Bacon

There’s something incredibly comforting about a warm, cheesy casserole — especially when it’s loaded with crisp bacon and tender cauliflower.

I made this cheesy cauliflower bake with bacon on a chilly Sunday evening, and it instantly became a family favorite.

It’s creamy, savory, and layered with textures that make every bite irresistible.

Why I Love This Cheesy Cauliflower Bake

What I love most about this bake is how effortlessly it brings comfort to the table.

The combination of creamy cheddar, salty bacon, and tender cauliflower is nostalgic yet fresh.

It’s one of those recipes that feels indulgent but still packs in a good serving of veggies.

Plus, it reheats beautifully, which means it’s perfect for meal prepping or next-day lunches.

What You’ll Need (Ingredient Highlights)

Cauliflower: The star of the dish! When baked in cheese sauce, cauliflower becomes buttery and satisfying.

Bacon: Adds a smoky crunch to every bite. You can cook it ahead for convenience.

Cheddar & Parmesan Cheese: The ultimate cheesy duo — cheddar for creaminess, parmesan for that savory punch.

Milk + Flour: Creates a quick roux for the base of the cheese sauce.

Garlic and Onion: Adds an aromatic base that rounds out the flavor.

Chives: Fresh, mild onion flavor and a pop of color for garnish.

Pro Tips Before You Start

Don’t overcook the cauliflower when boiling — it should still have some bite since it will continue to cook in the oven.

Whisk the milk and flour well before adding to the pan to avoid lumps.

Use freshly grated cheese for the smoothest, creamiest sauce.

Reserve some bacon for sprinkling on top — it adds visual appeal and crunch.

How to Make Cheesy Cauliflower Bake with Bacon

Step 1: Preheat the oven

Preheat your oven to 400°F (204°C).

Lightly grease an 8×8-inch baking dish and set aside.

Step 2: Cook the bacon

In a large skillet over medium heat, cook the chopped bacon until crispy.

Remove it with a slotted spoon and set aside on a paper towel-lined plate.

Reserve the bacon grease in the pan for extra flavor.

Step 3: Boil the cauliflower

Bring a large pot of water to a boil.

Add the cauliflower florets and cook for about 5 minutes, just until slightly tender.

Drain and set aside.

Step 4: Sauté the aromatics

Add olive oil to the reserved bacon grease in the skillet.

Sauté the onion and garlic over medium heat until fragrant and soft, about 3–5 minutes.

Step 5: Make the cheese sauce

In a small bowl, whisk together almond milk (or milk of choice) with the flour until smooth.

Pour this mixture into the skillet with the onion and garlic.

Bring to a gentle simmer and stir constantly.

Once it thickens slightly, stir in the cheddar, parmesan, and salt.

Mix until melted and creamy.

Step 6: Combine and assemble

Fold the cooked cauliflower into the cheese sauce until well coated.

Transfer the mixture to your prepared baking dish.

Sprinkle the crispy bacon evenly over the top.

Step 7: Bake

Place the dish in the oven and bake for about 20 minutes, or until bubbly and golden on top.

Step 8: Garnish and serve

Sprinkle with chopped chives and serve warm.

It’s rich, flavorful, and downright addictive!

What to Serve It With

As a side dish for roasted chicken or steak

Next to grilled sausages or pork chops

Alongside a fresh green salad for a lighter meal

Or as a main course with crusty bread to scoop up the creamy sauce

Variations / Substitutions

Make it vegetarian: Skip the bacon or use plant-based bacon bits.

Add heat: Stir in a pinch of cayenne pepper or red pepper flakes to the cheese sauce.

Swap cheeses: Try Gruyère or fontina for a richer melt.

Make it gluten-free: Use tapioca flour instead of all-purpose.

Storage & Leftovers

Let the casserole cool completely before storing. T

ransfer leftovers to an airtight container and refrigerate for up to 4 days.

To reheat: Warm in the oven at 350°F or microwave individual servings.

Add a splash of milk if the sauce thickens too much in the fridge.

This dish also freezes well. Just let it cool, wrap tightly, and freeze for up to 2 months.

Thaw overnight in the fridge and reheat in the oven.
