High-Protein Stuffed Mushrooms (Vegan, Smoky Quinoa & Tofu)
These high-protein stuffed mushrooms are baked until tender and packed with a smoky quinoa and tofu filling seasoned with smoked paprika, garlic, and fresh dill. They are completely vegan, naturally gluten-free and dairy-free, and work just as well as a hearty appetizer or a light main.
Big stuffed mushrooms always feel like an occasion, and this smoky quinoa-and-tofu filling makes them substantial enough to be a real meal, not just a nibble. The smokiness is what ties it together: a little smoked paprika goes a long way and makes the whole tray taste like it spent time over a fire. Choose large, flat caps, scrape out the dark gills for more room, and give the empty mushrooms a short pre-bake so they shed their water and never turn soggy.
Most stuffed mushrooms are a one-bite appetizer built on breadcrumbs and cheese. These are different. Cooked quinoa is a complete plant protein, crumbled firm tofu adds even more, and together they turn the filling into something genuinely hearty and satisfying. Smoked paprika and a spoon of tomato paste give it a deep, almost grilled, savoury flavour that reads far meatier than the ingredient list suggests. Pile it into big portobellos and you have a plate you can call dinner; spoon it into small caps and you have a protein-packed party bite.
Choosing and prepping the mushrooms
The mushroom is the vessel, so pick well. Large portobello caps make a substantial main, while cremini or large white button mushrooms are the right size for appetizers. Wipe them clean with a damp cloth rather than rinsing, since mushrooms soak up water, and twist out the stems (chop them and add them to the filling, nothing wasted). Scrape out the dark gills of portobellos for more room. The single most useful step is to pre-bake the empty caps for about ten minutes and pour off the liquid they release; do that and your stuffed mushrooms come out roasted, not watery.
The smoky quinoa and tofu filling
The filling comes together in one pan. Rinse the quinoa well before cooking to wash off its natural bitterness, and cook it ahead so it is cool and dry when you build the filling; leftover quinoa is perfect here. Press the firm tofu briefly, then crumble it in so it browns and crisps rather than steams. Soften onion and garlic, stir in tomato paste and smoked paprika and let them cook until deep and fragrant, then fold through the quinoa and plenty of fresh dill. For an even smokier result, add a few drops of liquid smoke or a pinch of chipotle.
Toppings, serving, and getting ahead
For a crisp, golden top, scatter over vegan parmesan, nutritional yeast, breadcrumbs, or chopped nuts before the mushrooms go back in the oven, and finish the tray with a squeeze of lemon or a thin drizzle of balsamic glaze to cut the richness. Serve them as an appetizer, or as a main with a green salad or a grain. They are made for getting ahead: stuff the caps a day in advance and bake just before serving, keep leftovers in the fridge for up to three days, and if you want to freeze, freeze the filling on its own for up to two months rather than the finished mushrooms.
For a simpler take, try my basic stuffed portobello mushrooms; this smoky quinoa-and-tofu version is the more protein-packed of the two. For more mushroom cooking, there is my creamy vegan mushroom risotto and a cosy creamy mushroom pie, or keep the stuffed theme going with couscous stuffed peppers and more high-protein vegan meals.

Notes
Frequently Asked Questions
Large portobello caps are best for a hearty main course because they hold a lot of filling. For appetizers, use cremini or large white button mushrooms. Just remove the stems and wipe the caps clean before stuffing.
Pre-bake the empty caps for about 10 minutes so they release their water first, then drain off any liquid before filling. Avoid washing them under running water; wipe them with a damp cloth instead.
Yes. You can prepare the quinoa and tofu filling and stuff the caps up to a day ahead. Keep them covered in the fridge and bake just before serving so they stay tender and warm.
The smoky flavor comes from smoked paprika and a little tomato paste cooked into the quinoa and tofu filling. You can add a few drops of liquid smoke or a pinch of chipotle for an even deeper smoky taste.
They are. Quinoa is a complete plant protein, tofu adds more protein and calcium, and mushrooms are low in calories and rich in B vitamins. Together they make a filling, balanced vegan dish.
Stuffed mushrooms are best fresh, since the caps soften after freezing. If needed, freeze the cooked quinoa and tofu filling on its own for up to 2 months, then thaw, stuff fresh caps, and bake.
