How to Make Stuffed Onions with Sun-Dried Tomatoes & Hazelnuts

Preheat the Oven: Begin by preheating your oven to 180°C (350°F). This ensures that your onions roast perfectly, transforming into soft, savory shells.
Prepare the Onions: Chop the tops off the large onions, exposing the inner layers. Wrap each onion in foil, securing them snugly, and roast them in the oven for 1 hour. This will soften them beautifully.
Roast the Hazelnuts: On a baking tray, spread the hazelnuts and roast them for about 5 minutes, or until fragrant and slightly golden. Watch closely to prevent burning!
Cook the Cous-Cous: In a saucepan, bring vegetable stock to a boil. Add the giant cous-cous, reduce the heat, and simmer for 6-8 minutes until tender. Drain and let it cool.
Mix the Filling: Finely chop the roasted hazelnuts, sun-dried tomatoes, and vegan feta. In a large bowl, combine these with the cooled cous-cous for a flavorful stuffing.
Season the Mixture: Sprinkle in salt, pepper, and dried chilli flakes while mixing gently. Taste and adjust the seasonings to suit your palate, ensuring a balanced flavor.
Stuff the Onions: Once the roasted onions are slightly cooler, peel them carefully. Scoop out the centers, and mix one-third of this onion flesh into your filling. Then, gently stuff each onion skin with the cous-cous mixture.
Add the Topping: If desired, sprinkle optional vegan cheese on top of each stuffed onion. This step adds extra creaminess that pairs wonderfully with the filling.
Bake to Perfection: Return the stuffed onions to the oven and bake them uncovered for an additional 15 minutes. They should be bubbling and golden on top when ready.

Optional: Garnish with fresh herbs before serving for an extra touch of flavor and color.

Stuffed Onions with Sun-Dried Tomatoes & Hazelnuts Recipe FAQs

What type of onions are best for stuffing?
Absolutely! Large onions, such as red or white varieties, are perfect for stuffing. Their size provides ample space for holding a generous filling. Look for onions that are firm and free of dark spots—this ensures they will hold their shape after roasting.

How should I store leftover stuffed onions?
Very! Once you’ve enjoyed your delicious stuffed onions, store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy them again, reheat gently in the oven or microwave to maintain their delightful texture.

Can I freeze the stuffed onions? If so, how?
Definitely! To freeze your stuffed onions, first wrap them tightly in plastic wrap or aluminum foil, then place them in a freezer-safe container or bag. They can be frozen for up to 3 months. When you’re ready to cook, thaw them overnight in the refrigerator, then bake as directed for a tasty meal.

What should I do if my filling is too dry or too wet?
If your filling turns out too dry, you can add a splash of vegetable stock or a drizzle of olive oil to moisten it up. For a filling that’s too wet, try adding a bit more giant cous-cous or some breadcrumbs to absorb the excess moisture. Always taste the mixture before stuffing to ensure balanced flavor and consistency.

Are there any allergenic ingredients in this recipe?
Yes, there may be potential allergens depending on your ingredients. The hazelnuts can be replaced with walnuts for a similar flavor, but always ensure any substitutes fit your dietary needs. Some brands of vegan feta may contain nuts, so make sure to check labels if you’re accommodating nut allergies. As always, consult with your guests about any specific dietary restrictions before serving.
