Ingredients

For the Wellington:

• 2 medium sweet potatoes, peeled and cubed
• 1 large onion, thinly sliced
• 2 tablespoons olive oil
• 2 tablespoons fresh thyme, chopped (or 1 tablespoon dried thyme)
• 1 teaspoon ground cumin (optional, for added depth of flavor)
• Salt and pepper, to taste
• 1 package puff pastry (usually comes with 2 sheets)
• 1 egg, beaten (for egg wash)
• 1 tablespoon balsamic vinegar (optional, for added sweetness and tang)
• Fresh herbs (like parsley or rosemary), for garnish (optional)

For the optional filling variations:

• 1 cup spinach (fresh or frozen), chopped
• 1/4 cup goat cheese or feta (for a creamy, tangy addition)
• 1/4 cup cooked quinoa or lentils (for added protein and texture)

Step-by-Step Instructions

Step 1: Roast the Sweet Potatoes

Start by preheating your oven to 400°F (200°C). While the oven is heating up, peel and cube the sweet potatoes. Place them on a baking sheet, drizzle with 1 tablespoon of olive oil, and sprinkle with a pinch of salt and pepper. Toss to coat the potatoes evenly.

Roast the sweet potatoes in the preheated oven for about 25 minutes, or until they are fork-tender and slightly caramelized. For an added depth of flavor, you can toss the sweet potatoes with ground cumin and fresh thyme before roasting. Once done, remove them from the oven and set aside to cool.

Step 2: Caramelize the Onions

While the sweet potatoes are roasting, heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the thinly sliced onions and sauté them, stirring occasionally, until they begin to soften and caramelize—this will take about 15-20 minutes. You want the onions to become golden brown and sweet, so be patient and don’t rush this step!

Once the onions are caramelized, drizzle them with 1 tablespoon of balsamic vinegar (optional), and season with salt and pepper to taste. This will add a bit of tanginess and extra flavor to the filling.

Step 3: Combine the Filling Ingredients

Once the sweet potatoes have cooled slightly and the onions are caramelized, it’s time to assemble the filling. In a large mixing bowl, combine the roasted sweet potatoes and caramelized onions. Use a fork or potato masher to mash the sweet potatoes slightly, but leave some chunks for texture.

Stir in the fresh thyme and adjust the seasoning with more salt and pepper, if needed. If you’re adding spinach, cheese, or grains, now is the time to mix them in. The spinach will add freshness, the cheese will bring a creamy, tangy element, and quinoa or lentils will provide extra texture and protein.

Step 4: Prepare the Puff Pastry

Roll out the puff pastry sheets on a clean, lightly floured surface. You want the sheets to be large enough to encase the filling, so if necessary, gently press the seams of the two sheets together to form one large rectangle.

Transfer the prepared filling onto the center of the pastry, spreading it out into an even line. Leave about 1 inch of space on the sides to allow for folding.

Step 5: Assemble the Wellington

Carefully fold the sides of the puff pastry over the filling, tucking the edges in and sealing it shut. Use a fork or your fingers to press the edges and seal them. You want to make sure the Wellington is tightly sealed so that the filling doesn’t leak out while baking.

Once the Wellington is sealed, turn it over so the seam side is facing down. If desired, use a sharp knife to lightly score the top of the pastry to create a decorative pattern. This will help the pastry cook evenly and give it a beautiful presentation.

Step 6: Apply the Egg Wash

Brush the top of the Wellington with the beaten egg to give it a golden, glossy finish when baked. This will also enhance the flaky texture of the puff pastry.

Step 7: Bake the Wellington

Place the assembled Wellington on a baking sheet lined with parchment paper. Bake it in the preheated oven at 400°F (200°C) for about 25-30 minutes, or until the puff pastry is golden brown and crispy.

Keep an eye on the Wellington as it bakes to ensure the pastry doesn’t burn. If it begins to brown too quickly, you can cover it loosely with aluminum foil and continue baking.

Step 8: Rest and Serve

Once the Wellington is baked to perfection, remove it from the oven and let it rest for about 5-10 minutes before slicing. This resting time allows the filling to set and makes it easier to slice without spilling.

Slice the Wellington into thick, hearty slices and garnish with fresh herbs like parsley or rosemary for a burst of color and freshness.

How to Serve

• As a Main Dish: Serve the Sweet Potato and Onion Wellington as the centerpiece of your meal, alongside roasted vegetables, a fresh salad, or mashed potatoes for a hearty vegetarian dinner.
• As Part of a Festive Feast: This Wellington is perfect for holiday meals, making it a great addition to your Thanksgiving or Christmas spread. Serve it alongside classic sides like green beans, cranberry sauce, and stuffing for a well-rounded meal.
• Slice for Appetizers: If you’re serving a crowd, consider slicing the Wellington into smaller, bite-sized pieces for an elegant appetizer or hors d’oeuvre.

Additional Tips and Variations

1. Make Ahead: You can prepare the Sweet Potato and Onion Wellington ahead of time. Assemble the Wellington, wrap it tightly in plastic wrap, and refrigerate it until ready to bake. When you’re ready, just brush it with the egg wash and bake as directed.
2. Vegan Option: To make this Wellington vegan, use a plant-based puff pastry (make sure it’s dairy-free) and replace the egg wash with a little olive oil or non-dairy milk.
3. Spicy Kick: For those who enjoy a bit of spice, try adding a pinch of cayenne pepper or a dash of smoked paprika to the filling for extra flavor.
4. **Add More Vegetables**: Feel free to add other vegetables to the filling, such as roasted bell peppers, mushrooms, or zucchini, for added variety and flavor.

Storage and Reheating

• Refrigeration: Leftovers can be stored in the refrigerator for up to 3 days. Reheat in a preheated oven at 350°F (175°C) for about 10-15 minutes to restore the crispness of the pastry.
• Freezing: You can also freeze the assembled but unbaked Wellington for up to 1 month. When ready to bake, simply brush with egg wash and bake from frozen, adding a few extra minutes to the baking time.

Conclusion

Sweet Potato and Onion Wellington is a perfect example of how a few simple ingredients can come together to create something truly spectacular. The combination of sweet, caramelized onions, hearty sweet potatoes, and flaky puff pastry makes for a dish that is both comforting and elegant. Whether you’re looking for a vegetarian main dish for a holiday meal or simply craving something delicious and different, this Wellington will deliver on both flavor and presentation.
