Sauce Ingredients
- 2 Tbs Butter
- 1/2 White Onion, sliced
- 2 Tbs All-Purpose Flour
- 2 Tbs Olive Oil
- 1 Cup Milk
- 1 Cup Pumpkin Purée
- 1/2 Tsp Black Pepper
- 1/2 Tsp Salt
- 1 Tsp Paprika
- Pinch of Nutmeg
- 2 Cups Shredded Gruyère or Swiss Cheese
Vegetables and Garnish
- 1 Small Head of Cauliflower, cut into florets
- Olive Oil for frying sage leaves (optional)
- Fresh Sage Leaves (optional, for frying)
- Preheat Oven: Preheat your oven to 425°F (220°C) to prepare for baking the gratin.
- Prepare Cauliflower: Cut the cauliflower head into small, bite-sized florets and set aside.
- Sauté Onions: In a large cast-iron or oven-safe skillet over medium-low heat, melt the butter. Add the sliced white onion and sauté until softened, about 5 minutes.
- Make Roux: Add olive oil and all-purpose flour to the pan. Stir continuously and cook for about 2 minutes, forming a smooth paste that will thicken the sauce.
- Add Milk and Pumpkin: Slowly add the milk while stirring. When milk begins to bubble, incorporate the pumpkin purée, salt, black pepper, paprika, and nutmeg. Stir until the mixture is smooth and combined.
- Add Cheese: Lower the heat to its lowest setting and add the shredded Gruyère cheese gradually, one handful at a time, stirring constantly. Be careful to keep the sauce smooth and avoid separation.
- Combine Cauliflower: Once the cheese sauce is smooth, add cauliflower florets to the skillet and mix to coat evenly with the sauce.
- Bake: Transfer the skillet directly to the preheated oven and bake for 25-30 minutes until the cauliflower is tender and the top is golden.
- Optional Broil: For extra browning and crispness, broil the gratin for 2-3 minutes after baking.
- Prepare Fried Sage (Optional): Heat 2-3 tablespoons of olive oil in a shallow pan over medium heat. Fry fresh sage leaves until fragrant and crispy, then remove and drain on paper towels.
- Serve: Garnish the gratin with fried sage if desired and serve warm.
Notes
- Use freshly shredded cheese instead of pre-shredded to avoid a grainy texture caused by anti-caking powders.
- Don’t skip sautéing the flour; it prevents the sauce from breaking.
- If the sauce breaks, cool it then blend until smooth to restore consistency.
- For gluten-free version, substitute all-purpose flour with gluten-free all-purpose flour.
- Broiling at the end enhances the gratin’s color and adds texture but watch carefully to prevent burning.
