What is a Gratin?
A Gratin is a dish where food is topped with a browned crust that usually contains cheese, breadcrumbs, or butter. I’ve become a huge fan of cheesy gratin dishes like this, and don’t think any breadcrumbs are needed!
Can you use other types of cheese for Broccoli Gratin?
If you don’t like Swiss Cheese or have other cheese on hand, you can use any white cheese that melts well for this recipe.
Can this recipe be made ahead?
I haven’t ever made this Broccoli Gratin too far ahead, but you can definitely blanch the broccoli and store it in the fridge for the day while you prepare the rest of the meal. Let the broccoli come to room temperature before you bake.

This Broccoli Gratin with Swiss and Parmesan cheese is a great option for a an easy and delicious Thanksgiving side dish.
- 8 cups bite-size broccoli flowerets
- 1 1/2 cups finely grated Swiss cheese
- 8 T mayo
- 1 1/2 T fresh squeezed lemon juice
- 3/4 tsp. Dijon mustard
- fresh ground black pepper to taste
- 3 T finely chopped green onions
- 1/4 cup finely grated Parmesan cheese
- Preheat oven to 375F.
- Bring large pot of salted water to a boil while you trim broccoli and cut into small flowerets. (I leave on a fair amount of the stem, but if stems are thick I recommend peeling some of the stem with a vegetable peeler.)
- When water starts to boil, put broccoli in and cook exactly 2 minutes (just until the broccoli turns bright green.)
- Immediately dump broccoli into a colander placed in the sink and let drain well.
- Spray a low-sided glass or crockery casserole dish with non-stick spray or olive oil.
- Put broccoli in casserole dish, spreading out into close to a single layer.
- Stir together mayo, lemon juice, Dijon mustard and black pepper, then mix in finely chopped green onion and finely grated Swiss cheese.
- Spread mayo-cheese mixture over the top of broccoli (I used a rubber scraper to do this. This is not a sauce that will completely cover the broccoli, but a thin layer of cheese sauce on the top.)
- Sprinkle parmesan cheese over mayo-cheese mixture.
- On Thanksgiving Day, this could be made ahead up to this point and kept in the refrigerator. Let come to room temperature before baking.
- Bake uncovered for about 30 minutes, or until cheese is melted and slightly browned on top. (I baked the broccoli gratin in the photos for exactly 32 minutes.
- Serve hot.
