Ingredients

1 butternut squash, halved (about 1 kg)
1 shallot, chopped
150 g button mushrooms (or wild mushrooms), finely chopped
1 handful of fresh chives, chopped
1 cup (100 g) grated cheese (Emmental, Comté, or mozzarella)
1 teaspoon mustard
100 ml liquid cream (or plant-based cream)
Salt and pepper, to taste
Olive oil, for drizzling

Kitchen Tools Needed

Baking tray
Sharp knife
Mixing bowl
Pan
Spoon for mixing

Step-by-Step Instructions

Preheat the oven to 180°C (350°F).
Cut the butternut squash in half lengthwise and scoop out the seeds. Drizzle lightly with olive oil.
Place the squash halves cut side down on a baking tray and roast in the oven for about 40 minutes.
Once roasted, scoop the flesh of the butternut squash into a mixing bowl and set aside.
In a pan, heat a drizzle of oil over medium heat and cook the chopped shallot for about 3 minutes, or until translucent.
Add the mushrooms to the pan and sauté for an additional minute over low heat until softened.
Mix in the reserved butternut squash flesh and cook for 5-6 minutes until everything is well combined.
Pour in the cream, add the chopped chives, mustard, salt, and pepper. Stir well to combine.
Stuff the hollowed butternut squash halves with the mushroom mixture.
Top each filled squash half with a generous sprinkle of grated cheese.
Bake the stuffed squash halves at 200°C (400°F) until the cheese is golden brown, about 15-20 minutes.
Serve hot, and enjoy this creamy and flavorful gratin.

Pro Tips

Ensure the mushrooms are finely chopped for even cooking.
Roast the squash until fork-tender for the best texture.
For a golden top, broil the gratin for the last few minutes of baking.

Lighter Swaps

Substitute the cream with a lighter coconut milk for a less rich dish without sacrificing flavor.
Use less cheese or a sprinkle of nutritional yeast for a flavorful, lower-calorie option.

Common Mistakes

Skipping the step of roasting the squash could lead to a watery final dish.
Overcooking the mushrooms can result in a rubbery texture.

Serving Suggestions

Pair this gratin with a green salad or serve alongside grilled chicken for a well-rounded meal.

Storage Instructions

Store leftovers in an airtight container in the fridge for up to three days.
