Step 1: Prepare the stock.
Simmer the porcini mushroom in boiling water for 5 minutes and set aside.
Step 2: Prepare the onions.
Peel each whole onion carefully. With a sharp knife, cut the tops and bottoms of the onions.
Then cut top to bottom, placing the knife's tip at the center of the onion.
Remove the onion's inner flesh and reserve it for the stuffing.
Hint: carefully remove the inner layers (onion flesh), reserve the onion flash for another use, or chop centers and replace the spring onions for the stuffing.
Remove the outer layers carefully.
The smaller the holes, the better.
Step 3. Briefly cook the onion's outer layers.
Take off the porcini mushrooms from the saucepan and add the white wine, 1 cup at a time. Simmer for a few minutes, and briefly cook the onion layer, a few at a time. They should not cook much. They only need to be a little tender, as the cooking process will finalize in the oven.
Set aside and let them cool, as you will handle them later with your hands.
Preheat oven to medium-high heat, 350 ºF (175ºC).
Step 4: Making the vegan stuffing mix.
On a medium saucepan, stir the chopped stuffing ingredients, beginning with chopped onion and garlic, then the crumbled tofu, and chopped dried tomatoes, until you add all the remaining ingredients.
Mix everything, occasionally stirring, until you have a nice texture.
Hint: don't use a food processor; you need your stuffing textures! Add more liquid if needed.
Remove from heat and add the bread crumbs and nutritional yeast to the saucepan or a large bowl. Then season with a teaspoon of salt and ground black pepper.
Step 5: assemble the boiled onions with the vegetarian stovetop stuffing.
Prepare your table to start stuffing the onion shells and line a baking dish with cooking spray or just a little olive oil.
Stuff the onions with the help of a spoon and secure them with a toothpick.
Step 5. baking stove top stuffing inside of the onions.
Your stuffed onions recipe will be ready after 45-50 minutes. The stuffed onions are best served warm.

These baked stuffed onions can make an excellent side dish. If you want to serve these roasted onions recipes as the main dish, we suggest calculating two per person.
I recommend using a pretty baking dish for cooking this porcini recipe, you can even plate the onions using the same dish. If you do so, use a glass or ceramic one.
- Tartness - If you like to add some additional festive and tart notes to your stuffing, you can add a handful of dried cranberries to the stuffing while it cooks.
- Stuffing volume - You can also add cooked rice to your stuffing to make it bigger. Adjust the seasoning accordingly.
- Onions - Sweet onions also work well for this stuffed onions recipe. After you separate the onion shells, the spring onions can be replaced by the remaining onions.
- Gluten-free - you can omit the bread crumbs or use gluten-free breadcrumbs. If you skip them, we suggest making a chia egg or flax egg with 1 tablespoon of chia seeds plus 3 warm water. This will help to thicken the stuffing. Also, you should add them while the filling is still being cooked.
It’s a great recipe for friends and family because it can be made ahead, refrigerated overnight, or frozen in advance.
Store leftover onions in the fridge for up to 3 days, covered in an airtight container.
Freeze the tofu stuffing and keep it for up to 2 months. To use it, let it thaw overnight and use it on your favorite stuffed vegetable recipes, such as stuffed peppers, pasta shells, stuffed zucchini, or eggplants.
You can also have the stuffing with an Italian bread loaf, focaccia bread, cornbread, stuffing, or vegan bread buns.

First, you have to make sure you are buying an authentic product. Many products are available in markets with very few mushrooms, so you should be careful when buying them.
Porcini mushrooms have a fresh earthy smell; the younger they are, the more intense their flavor will be. You can use them for cooking different meals, like pasta, stuffing, and casseroles.
This mushroom's special flavor and fragrance make it one of Italy’s favorite pickings during autumn, but its price forces one to choose between fresh porcini mushrooms or dried ones.
