Ingredients for Crispy Boursin Spinach Gratin
- 2 (10 oz) bags frozen chopped spinach, thawed and drained
- 1 (5.2 oz) package Garlic & Fine Herbs Boursin cheese, cubed
- ½ cup heavy cream
- ½ cup shredded Gruyère or Swiss cheese
- ¼ cup grated Parmesan cheese
- 3 tablespoons unsalted butter, divided
- ½ cup panko breadcrumbs
- 1 small yellow onion, diced
- 2 cloves garlic, minced
- ¼ teaspoon ground nutmeg
- 1 teaspoon kosher salt

How to Make Crispy Boursin Spinach Gratin: Step-by-Step Directions
Step 1: Prep Your Spinach
Preheat your oven to 400°F (200°C). Squeeze the thawed spinach in a clean kitchen towel to remove as much excess water as possible—this keeps your gratin perfectly creamy, not watery.
Step 2: Sauté the Aromatics
In a large skillet over medium heat, melt 1 tablespoon butter. Add the diced onion and cook until soft (about 3-4 minutes). Stir in the garlic and cook for 1 more minute, until fragrant.
Step 3: Combine and Add Cheeses
Stir the spinach into the skillet. Season with nutmeg, salt, and pepper. Mix in the heavy cream, then fold in the Boursin cheese cubes. Cook for 2-3 minutes, stirring, until the cheese is mostly melted. Remove from heat and toss in the Gruyère or Swiss cheese until combined.
Step 4: Assemble the Gratin
Transfer the spinach mixture to a lightly greased 2-quart baking dish. Sprinkle the Parmesan evenly on top.
Step 5: Prepare the Crispy Topping
Melt the remaining 2 tablespoons butter and mix with the panko breadcrumbs in a small bowl. Sprinkle the buttery panko evenly over the gratin.
Step 6: Bake to Perfection
Bake on the middle rack for 18-22 minutes, until the top is golden brown and bubbly. For extra browned topping, broil for 2-3 minutes at the end—just keep a close eye!
