Ingredients List

To create your Caramelized Onion Butternut Squash Tart, gather the following ingredients:

• 1 medium butternut squash, peeled and cubed
• 2 large onions, thinly sliced
• 2 tablespoons olive oil
• 1 tablespoon balsamic vinegar
• 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme)
• 1 pre-made pie crust (store-bought or homemade)
• 3 large eggs
• 1 cup heavy cream (or a dairy-free alternative)
• 1 cup grated Gruyère cheese (or cheddar for a sharper flavor)
• Salt and pepper to taste

Substitutions:

• Butternut Squash: Sweet potatoes or pumpkin can be used as alternatives.
• Gruyère Cheese: Feta or goat cheese can provide a tangy twist.
• Heavy Cream: Use coconut milk or cashew cream for a lighter option.

Step-by-Step Instructions

Step 1: Roast the Butternut Squash

Preheat your oven to 400°F (200°C). In a bowl, toss the cubed butternut squash with 1 tablespoon of olive oil, salt, and pepper. Spread the squash on a baking sheet and roast for about 25 minutes, or until tender and slightly caramelized. This step enhances the natural sweetness of the squash.

Step 2: Caramelize the Onions

While the squash is roasting, heat the remaining tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for about 15-20 minutes until they are soft and golden brown. Stir in the balsamic vinegar and thyme, cooking for an additional 2 minutes. This process deepens the flavor profile of the tart.

Step 3: Prepare the Tart Shell

If using a store-bought pie crust, follow the package instructions for pre-baking. If making homemade dough, roll it out and fit it into a tart pan. Prick the bottom with a fork to prevent bubbling.

Step 4: Combine Ingredients

In a mixing bowl, whisk together the eggs and heavy cream. Stir in the roasted butternut squash, caramelized onions, and half of the Gruyère cheese. Season with salt and pepper to taste.

Step 5: Assemble and Bake

Pour the filling into the prepared tart shell and sprinkle the remaining Gruyère cheese on top. Bake in the preheated oven for 30 minutes or until the tart is set and golden brown on top.

Step 6: Cool and Serve

Allow the tart to cool for 10 minutes before slicing. This cooling period helps the filling set further, making it easier to serve.

Common Mistakes to Avoid

To ensure your tart turns out perfectly, avoid these common pitfalls:
