Ingredients
1 tart crust (homemade or store-bought)
2 cups butternut squash, peeled and cubed
2 large yellow onions, thinly sliced
2 tablespoons olive oil
1 tablespoon butter
1 teaspoon fresh thyme leaves
3 large eggs
3/4 cup heavy cream
1/2 teaspoon salt
1/4 teaspoon black pepper
1/3 cup crumbled blue cheese
Instructions
1. Preheat oven to 400°F (200°C). Toss cubed butternut squash with 1 tablespoon olive oil, salt, pepper, and thyme. Roast on a baking sheet for 25 minutes until tender and golden.
2. Meanwhile, heat a skillet over medium-low heat. Add 1 tablespoon olive oil and butter. Add sliced onions and cook for 30-40 minutes, stirring often, until deep golden and caramelized.
3. Blind bake tart crust: Preheat oven to 375°F (190°C). Line the crust with parchment paper and weights. Bake for 15 minutes, remove weights, then bake 10 more minutes until lightly golden.
4. In a bowl, whisk together eggs, heavy cream, salt, and pepper. Stir in half of the caramelized onions and half of the roasted squash.
5. Pour the mixture into the tart crust. Top with remaining onions, squash, and crumbled blue cheese.
6. Bake at 375°F (190°C) for 30-35 minutes or until the filling is set. Cool slightly before slicing.
Notes
Use room temperature eggs and cream for even mixing.
Caramelize the onions ahead of time to save prep.
