Ingredients
- 1 large head of cauliflower, cut into florets
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- Salt and freshly ground black pepper, to taste
- 1 cup shredded sharp cheddar cheese
- ½ cup grated Parmesan cheese
- 1 cup whole milk (or any unsweetened plant-based milk for a dairy-free option)
- 2 tablespoons unsalted butter (or plant-based butter alternative)
- 2 tablespoons all-purpose flour (or gluten-free flour)
- 1 teaspoon Dijon mustard
- Fresh parsley, chopped, for garnish (optional)
How To Make Cheesy Roasted Cauliflower Recipe
Step 1: Preheat and Prepare Cauliflower
Start by preheating your oven to 425°F (220°C). While the oven heats, wash and cut your cauliflower into medium-sized florets. Place the florets in a large bowl, then drizzle with olive oil, garlic powder, smoked paprika, salt, and pepper. Toss well to ensure every floret is evenly coated with the seasoning.
Step 2: Roast the Cauliflower
Spread the seasoned cauliflower florets in a single layer on a baking sheet lined with parchment paper or a silicone mat. Roast in the preheated oven for about 25-30 minutes, flipping halfway through to promote even browning. The cauliflower should be tender and golden brown on the edges once done.
Step 3: Make the Cheese Sauce
While the cauliflower roasts, prepare the cheese sauce. In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for about 1-2 minutes to form a roux, stirring constantly to avoid burning. Slowly pour in the milk while whisking continuously to prevent lumps. Continue cooking and stirring until the mixture thickens, about 5 minutes.
Step 4: Add Cheese and Seasonings
Remove the saucepan from heat and stir in the shredded cheddar, grated Parmesan, and Dijon mustard. Mix until the cheese is fully melted and the sauce is smooth. Taste and adjust seasoning with salt and pepper as needed.
Step 5: Combine and Bake
Once the cauliflower is roasted, transfer the florets to a baking dish. Pour the cheese sauce evenly over the cauliflower, ensuring all pieces are well coated. Return the dish to the oven and bake for an additional 10 minutes, or until the cheese sauce is bubbly and slightly golden on top.
Step 6: Garnish and Serve
Remove from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley for a pop of color and freshness. Serve warm as a side dish or a comforting snack.
Expert Tips
- For extra crispy edges, roast cauliflower on a high temperature and avoid overcrowding the pan.
- Use freshly grated cheese for a smoother, creamier sauce; pre-shredded cheese often contains anti-caking agents that can affect texture.
- If you prefer a thicker cheese sauce, add a little more flour when making the roux or reduce the milk slightly.
- For added depth, toss the cauliflower with a pinch of cayenne or chili powder before roasting.
- Don’t skip tossing the cauliflower halfway through roasting to ensure even caramelization.
- Feel free to add a squeeze of fresh lemon juice on top before serving for a bright, tangy finish.
Variations and Customizations
- Spicy Kick: Add red pepper flakes or a dash of hot sauce to the cheese sauce for a spicy twist.
- Herb Infusion: Mix in fresh herbs like thyme, rosemary, or chives into the cheese sauce or sprinkle on top before baking.
- Different Cheeses: Swap cheddar and Parmesan with mozzarella, Gruyère, or pepper jack for varied flavors.
- Vegan Option: Use plant-based butter, unsweetened almond or oat milk, and vegan cheese shreds.
- Add Crunch: Top with toasted breadcrumbs or crushed nuts before the final bake for a delightful crunch.
- Protein Boost: Stir in cooked, diced chicken or chickpeas to turn this into a more filling main dish.
How to Store Leftovers
Store any leftover Cheesy Roasted Cauliflower in an airtight container in the refrigerator for up to 3 days. To reheat, place it in a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through and the cheese sauce is bubbly again. Alternatively, you can microwave it, but the oven method helps maintain the texture better. Avoid storing at room temperature to keep it fresh and safe to eat.
