๐ Ingredients & substitutions
- Acorn squash: Known for its sweet, nutty flavor, acorn squash is perfect for roasting. Look for medium-large squash. If you canโt find acorn squash, try butternut squash or delicata squash for a similar taste and texture.
- Olive oil: Adds a rich flavor and browns the squash while roasting. Avocado, grapeseed, sunflower, or safflower oil all work too.
- Onion: Provides a sweet, aromatic base. White or yellow onions are ideal, but you can also use red onions or shallots if you prefer.
- Cremini mushrooms: Impart an earthy flavor to the filling. Portobello, button mushrooms, or shiitakes are other great options.
- Garlic: Adds depth and a savory aroma. Use garlic powder if fresh isnโt available.
- Walnuts: Bring a crunchy texture and nutty taste. Pecans, almonds, pumpkin seeds, hemp hearts, or sunflower seeds will also work.
- Tamari: Enhances the savory, umami flavors. You can use liquid aminos, or try coconut aminos for a soy-free option. Alternatively, soy sauce works if youโre not gluten-free.
- Quinoa: Adds bulk and a punch of protein. Feel free to use white or tricolor quinoa. Cooked brown rice or bulgur are also delicious.
- Chickpeas: Provide plant-based protein and texture. You can also try cooked green or brown lentils, cannellini beans, or black beans.
- Dried cranberries: Offer a hint of sweetness and a chewy texture. Raisins or chopped dried apricots would also make the perfect addition.
- Fresh thyme: Adds an earthy, slightly minty flavor. You can substitute dried thyme, but use less as itโs more concentrated. Or, try rosemary or sage.

๐ How to make vegan stuffed acorn squash
Step 1: Roast the squash
Preheat your oven and get your acorn squash ready by slicing, seeding, and seasoning them. Brush them with olive oil and a generous sprinkle of salt and pepper.


Place the squash halves on a baking sheet, face down, and roast them until they’re tender. This brings out their natural sweetness and softens them perfectly for stuffing.
Step 2: Make the filling
In a skillet, cook the onions and mushrooms until theyโre both tender. Then, stir in the garlic and walnuts before adding the rest of the filling ingredients. Let everything cook for a few minutes to allow the flavors to meld.


Step 3: Stuff & bake everything
Once the squash is roasted and the filling is ready, spoon the mixture into each half. Return your vegan stuffed acorn squash to the oven for a final bake. Before serving, sprinkle each half with freshly chopped parsley for a pop of color. Happy eating!
