• Meal-prep friendly: The casserole holds up well in the fridge and freezer, making leftovers a plus.
• Customizable flavors: Swap cheeses, add spices, or toss in greens—this base plays well with many variations.

Ingredients

• 1 large head cauliflower, cut into small florets (about 6–7 cups)
• 2 cans (15 oz each) chickpeas, drained and rinsed
• 1 small yellow onion, finely chopped
• 3 cloves garlic, minced
• 2 tablespoons olive oil
• 1 teaspoon smoked paprika
• 1 teaspoon dried thyme (or Italian seasoning)
• 1/2 teaspoon crushed red pepper flakes (optional)
• Salt and black pepper to taste
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups low-sodium milk (2% or whole)
• 1 cup low-sodium vegetable broth (or chicken broth)
• 1 teaspoon Dijon mustard
• 1/2 cup plain Greek yogurt (or sour cream)
• 1 1/2 cups shredded sharp cheddar cheese
• 1/2 cup grated Parmesan cheese
• 1/2 cup whole-wheat panko or regular breadcrumbs
• 2 tablespoons chopped fresh parsley or chives (optional, for garnish)

Instructions

1. Preheat and prep: Heat the oven to 425°F (220°C).

   Lightly grease a 9×13-inch baking dish.

2. Season the veg: On a large sheet pan, toss the cauliflower and chickpeas with olive oil, onion, garlic, smoked paprika, thyme, red pepper flakes (if using), and a generous pinch of salt and pepper.
3. Roast: Spread in an even layer and roast for 22–25 minutes, stirring halfway, until the cauliflower is golden at the edges and the chickpeas are slightly crisp.
4. Start the sauce: In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly.
5. Add liquids: Slowly whisk in the milk, then the broth, a splash at a time to avoid lumps. Bring to a gentle simmer and cook 3–4 minutes until slightly thickened.
6. Flavor and enrich: Whisk in the Dijon, a pinch of salt and pepper, and remove from heat.

   Stir in the Greek yogurt until smooth.

7. Cheese it up: Add 1 cup cheddar and 1/4 cup Parmesan to the warm sauce. Stir until melted and silky.
8. Combine: Transfer the roasted cauliflower and chickpeas to the prepared baking dish. Pour the cheese sauce over and fold gently to coat.
9. Top: Mix the breadcrumbs with the remaining cheddar and Parmesan.

   Sprinkle evenly over the casserole.

10. Bake: Lower the oven to 375°F (190°C). Bake for 18–22 minutes, until bubbling at the edges and the top is golden.
11. Rest and serve: Let it sit for 10 minutes to set. Sprinkle with fresh parsley or chives if you like.

Storage Instructions

• Refrigerate: Cool completely, then cover tightly.

  Keeps 4 days in the fridge.

• Reheat: Warm individual portions in the microwave or reheat the whole dish at 325°F (165°C) for 15–20 minutes, covered with foil.
• Freeze: Freeze in airtight portions for up to 2 months. Thaw in the fridge overnight before reheating.
• Make-ahead: Assemble up to the breadcrumb topping, cover, and refrigerate up to 24 hours. Add the topping and bake when ready.

Why This is Good for You

• Fiber-rich: Chickpeas and cauliflower provide both soluble and insoluble fiber to support digestion and steady energy.
• Protein boost: Chickpeas and dairy team up for a satisfying protein profile that helps keep you full.
• Smart fats: Olive oil and moderate cheese give flavor and satiety without going overboard.
• Micronutrient perks: Cauliflower brings vitamin C and K, while chickpeas add iron, folate, and magnesium.
• Lower refined carbs: You get comfort food vibes with far less starch than traditional pasta-based casseroles.

Pitfalls to Watch Out For

• Watery casserole: If cauliflower crowded on the pan steams instead of roasts, you’ll get extra moisture.

  Use a large sheet pan and roast at high heat.

• Broken sauce: Overheating after adding yogurt can cause curdling. Take the sauce off the heat before stirring in yogurt and cheese.
• Bland seasoning: Cauliflower needs a firm hand with salt. Taste the sauce and the roasted veg so the flavors pop.
• Soggy topping: Add breadcrumbs just before baking, and avoid covering with foil during the last bake so it crisps.
• Gritty cheese: Pre-shredded cheese can be coated with anti-caking agents.

  For the smoothest sauce, grate cheese from a block.

Recipe Variations

• Spinach and Artichoke: Stir in 2 cups chopped baby spinach and 1 cup chopped marinated artichoke hearts right before baking.
• Spicy Buffalo: Add 2–3 tablespoons hot sauce to the sauce and use Monterey Jack instead of cheddar. Top with sliced green onions.
• Herby Lemon: Add 1 tablespoon lemon zest and 2 tablespoons chopped fresh dill or basil to the sauce for a bright twist.
• Smoky Bacon (or Tempeh Bacon): Fold in 1/2 cup cooked crumbled bacon or crispy tempeh bacon for savory crunch.
• Extra Veg: Roast sliced mushrooms or zucchini alongside the cauliflower and add to the casserole for extra bulk.
• Gluten-Free: Use a 1:1 gluten-free flour for the roux and gluten-free breadcrumbs.
• Dairy-Light: Use reduced-fat milk and half the cheese; add 2 tablespoons nutritional yeast for savory depth.

FAQ

Can I make this casserole vegan?

Yes. Use vegan butter, a plant-based milk that’s unsweetened and unflavored, and a good melting vegan cheese.

Swap the yogurt for plain unsweetened dairy-free yogurt or 1–2 tablespoons cashew cream.

Do I need to pre-cook the cauliflower?

Roasting is the pre-cook step here. It concentrates flavor and reduces moisture so the casserole doesn’t turn watery. Skip boiling or steaming.

What can I use instead of chickpeas?

White beans, like cannellini or great northern, work well.

They’re creamy and mild, and they blend seamlessly with the cheese sauce.

How do I get a thicker sauce?

Simmer the milk and broth mixture a minute or two longer before adding yogurt and cheese. You can also increase flour to 3 tablespoons for a sturdier base.

Can I add cooked chicken?

Absolutely. Fold in 1–2 cups shredded cooked chicken before baking.

Reduce salt slightly if your chicken is seasoned.

Will frozen cauliflower work?

It can, but thaw and pat dry first, and roast a little longer to drive off moisture. Fresh cauliflower gives the best texture.

How spicy is it?

With just a pinch of red pepper flakes, it’s mild. Leave them out for a kid-friendly version, or add more for heat lovers.

Can I assemble and freeze before baking?

Yes.

Assemble without the breadcrumb topping, wrap tightly, and freeze. Thaw overnight, add the topping, and bake until hot and bubbly.

What cheese melts best here?

Sharp cheddar gives classic flavor and melts well. Gruyère, fontina, or a mild provolone also melt beautifully and add complexity.

How can I make the topping extra crispy?

Toss the breadcrumbs with a teaspoon of olive oil before sprinkling on.

Broil for 1–2 minutes at the end, watching closely to prevent burning.
