Roasted Portobello Mushrooms with Walnut Coffee Sauce- a healthy delicious, vegan version or “steak and gravy” – but plant-based & quick, easy and delicious! Serve as a vegan main dish with cauliflower mash or roasted garlic mashed potatoes!
After the holidays this year, Brian and I decided to try to eat mostly plant-based meals for the month of January, just to give our bodies a little break. Lots of soups and stews happening around here and of course healthy fresh buddha bowls and vegan salads! But because it is still so cold here, we’ve especially been craving heartier cozy meals too.
This is how this recipe for Roasted Portobello Mushrooms with Walnut Coffee Sauce came to be. Served over a bowl of creamy cauliflower mash, it is rich and heavenly, a “stick-to-your-bones” kind of meal, while remaining completely vegan. It is also a snap to make.
(And don’t the let the “coffee” part scare you. You can’t actually taste the coffee at all- but it does add a degree of depth and nuance that adds delicious umami flavor. But no, nothing like your morning coffee.) I asked my husband what he thought was in the sauce and he said “beef”. Never did he guess there was coffee in this. 😉
This week I’ve partnered with California Walnuts to create this cozy wintry dinner. The addition of walnuts gives the sauce such a delicious depth and richness- not to mention protein (4 grams/ounce) and healthy, plant-based fats (13g/oz polyunsaturated and 2.5g/oz monounsaturated fat) while keeping this completely vegan. It tastes “meaty”! Walnuts, if you didn’t know, have zero cholesterol and are the only nut with a significant amount of plant-based omega-3 ALA (2.5 grams/ounce).
To roast portobello mushrooms, preheat oven to 400 F.
Brush the portobello mushrooms with a mixture of olive oil and balsamic vinegar, and sprinkle with salt and pepper, and place gill-side down, on a parchement-lined sheet pan for 20-25 minutes (depending on their size).
While the Portobello mushrooms are roasting, make the walnut sauce. Sauté the shallots and garlic in a pan until fragrant and golden, then add the walnuts and coffee, de-glazing the pan.
Then blend until smooth with the remaining seasonings. So very simple!
You’ll end up with a flavorful walnut “gravy” or sauce.
Wild rice would also be a good option here too!
Scatter some pomegranate seeds over top of the roasted portobellos, for a splash of color, bright flavor and great texture if you like!
Add a few sprigs of time, an optional drizzle of truffle oil ….and there you go!
A hearty, satisfying wintery meal that is vegan and gluten-free! I hope you like these Roasted Portobellos with Walnut Sauce as much as we have!!!
Have a great week.
