Introduction
Broccoli gratin is one of those comforting dishes that feels indulgent without being fussy. This bake brings together bright, crisp broccoli with a creamy cheese sauce and a golden crumb topping. It’s versatile, family-friendly, and easy to tailor to the ingredients you have on hand. Whether you’re cooking for a weeknight supper or a casual weekend dinner, this dish adds a touch of elegance to the table without requiring advanced kitchen skill.
Why this dish works
The appeal of broccoli gratin lies in contrast: tender broccoli against a velvety sauce, a little nutty cheese flavor, and a crisp topping. The process is simple, and the result is satisfying enough to stand beside proteins like roast chicken, baked fish, or a hearty grain salad. You can adapt the cheese, add a hint of mustard, or toss in extras like cooked ham, mushrooms, or thinly sliced onions to suit your taste.
Ingredients
- 1 lb (450 g) broccoli florets, cut into bite-sized pieces
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 1 1/2 cups (360 ml) milk, whole milk preferred
- 1/2 cup heavy cream (optional, for extra richness)
- 1 cup grated cheese (a mix of Gruyère and cheddar works well; you can use all Gruyère for a sharper bite)
- 1/4 teaspoon salt, freshly ground black pepper, to taste
- Pinch of ground nutmeg (optional)
- 1/2 cup breadcrumbs or panko
- 2 tablespoons grated Parmesan (for topping)
- 1 tablespoon olive oil (for the topping, optional)
Method
Prepare and preheat
Preheat your oven to 375°F (190°C). Lightly butter a shallow baking dish to prevent sticking. If you like a greener, crisper finish, you can reserve a few broccoli florets to scatter on top after assembling and before baking.
Blanch the broccoli
Bring a pot of salted water to a boil. Add the broccoli florets and blanch for 2–3 minutes until bright green and slightly tender. Drain well and set aside. Blanching helps preserve color and texture and shortens the baking time.
Make the cheese sauce
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for about 1 minute to form a light roux. Gradually pour in the milk, whisking constantly to avoid lumps. If using cream, add it now. Simmer gently until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in most of the grated cheese (reserve a little for topping). Season with salt, pepper, and a pinch of nutmeg if you like.
Assemble
In the prepared baking dish, combine the broccoli with the cheese sauce until evenly coated. Pour and spread to create a flat surface. Sprinkle the remaining cheese over the top for a melty, cheesy crust.
Prepare the topping
In a small bowl, mix the breadcrumbs with Parmesan and a drizzle of olive oil to moisten. This helps the topping brown and stay crispy. Sprinkle the topping over the cheese layer.
Bake and finish
Bake for about 20–25 minutes, or until the sauce is bubbling and the top is golden and crisp. If you’d like a deeper golden crust, you can broil for 1–2 minutes at the end, watching closely to prevent burning. Let the gratin rest for 5–10 minutes before serving to allow the sauce to thicken slightly.
Variations and tips
Make it richer or lighter
- For a lighter version, use low-fat milk and omit the cream. The dish will still be creamy thanks to the cheese.
- For extra richness, use a full cup of cheese in the sauce and add a tablespoon of sour cream or crème fraîche toward the end for a tangy finish.
Cheese options
- Gruyère, cheddar, or fontina are reliable choices. A sharper cheese like aged cheddar adds depth, while a milder cheese keeps the flavor gentle. A small amount of Parmesan on top adds a nutty finish.
Add-ins and flavor boosters
- A clove of garlic, minced, or a teaspoon of Dijon mustard stirred into the sauce can brighten the dish.
- Sliced mushrooms, cooked ham, or cooked bacon can be folded into the broccoli before adding the sauce for a heartier gratin.
- A squeeze of lemon or a little lemon zest can bring a fresh contrast to the richness.
Make ahead and storage
- You can assemble the gratin up to a day in advance. Cover and refrigerate, then bake as directed, adding a few extra minutes for the chill.
- Leftovers store in an airtight container in the fridge for 3–4 days. Reheat gently in the oven or on the stove with a splash of milk to restore creaminess.
Serving suggestions
This dish pairs well with simple proteins and light greens. Try it alongside roast chicken, pan-seared salmon, or a simple quinoa salad. A bright side of tomato and cucumber salad or a peppery arugula salad can balance the richness and keep the meal feeling fresh.
