Ingredients
- 400 ml whipping or double cream (about 1 3/4 cups, avoid single or half and half cream)
- 2 bay leaves
- A handful of thyme sprigs
- 1 crushed garlic clove
- 1/2 teaspoon ground nutmeg
- 1 tablespoon butter
- 2 pounds thinly sliced butternut squash, peeled
- 100 grams grated mature white cheddar cheese (approximately 1 cup)
Instructions
- Step 1: Preheat your oven to 350°F (180°C). In a saucepan, combine the cream with nutmeg, crushed garlic, thyme sprigs, and bay leaves. Bring to a gentle boil over medium heat, then remove from heat and let the flavors infuse for 10-15 minutes.
- Step 2: While the cream infuses, peel, deseed, and slice the butternut squash evenly. Thoroughly butter a large, shallow ovenproof dish.
- Step 3: Layer half of the sliced squash in the dish. Pour half of the infused cream over this first layer. Add the remaining squash slices on top, then cover with the rest of the cream.
- Step 4: Cover the dish tightly with foil and bake for 30 minutes to soften the squash and meld flavors.
- Step 5: Remove the foil and sprinkle grated cheddar evenly on top. Return the dish to the oven, uncovered, and bake for another 20-30 minutes until the cheese is golden and the cream bubbles at the edges.
- Step 6: Let the casserole cool slightly before serving. Enjoy the rich, creamy squash gratin!
Tips & Variations
- For a dairy-free version, replace cream with full-fat coconut milk and use nutritional yeast instead of cheddar for a cheesy flavor.
- Substitute butternut squash with sweet potatoes or pumpkin for a similar texture and taste.
- Try Gruyère or Gouda cheese instead of cheddar for a different flavor profile.
- Use Greek yogurt instead of cream for a lower-fat, tangier option.
- Make sure squash slices are uniform in thickness to ensure even cooking.
Storage
Store leftovers covered in the refrigerator for up to 3 days. Reheat gently in the oven at 325°F (160°C) until warmed through to preserve the creamy texture. Avoid microwaving to keep the casserole from drying out.
