These juicy and tender grilled portobello mushroom steaks are AMAZING! They're quick (ready in 15 minutes!), easy, tasty and have all the best flavours of a smokey grilled steak, but vegan. The charred mushrooms have a lovely dense texture that's perfect with the flavourful simple marinade. Vegetarian, vegan and gluten free. Make them on the grill, grill pan, barbecue or in the oven.  #vegansteak #mushroomsteak #valentinesday #vegandinner #easyvegandinner #glutenfreevegan

If you're looking for a romantic vegan dinner for two, then you've come to the right place.

Heck, this dish is even perfect for a non-romantic, rushed post-work Wednesday dinner.

It's screams "I love you", but it's also quick, easy and tasty. 

This vegan Valentine's Day dinner is quick, easy and full of flavor.

You won't be slaving in the kitchen all day.

Instead it takes just a few minutes to prepare and a few minutes to cook.

You can have a vegan / vegetarian dinner for two on the table in just 15 minutes! 

When they cook, the mushrooms release their juices, which mingle with the marinade ingredients creating a lovely jus/sauce with concentrated steakhouse flavours.

But it's all vegan!

Serving Suggestions

Add some fries or mashed potato plus some green veg and you have a flavor-packed easy vegan dinner.

I love serving these mushroom steaks with roasted radishes!

Perfect for a romantic meal, or a quick midweek dinner.

Drizzle with a little Carrot Top Chimichurri or even Carrot Top Pesto.

Serve with a side of vegan mashed potatoes, swede and carrot mash or roasted swede.

Add a side of Zax Sauce or this Cane's Sauce Recipe. Both are flavor-packed dipping sauces.

Try it with a whole roasted cauliflower for a real showstopper of a meal.

Try with a drizzle of mushroom gravy or vegan gravy.

Serve with roasted garlic mashed potatoes, baby hasselback potatoes or parmentier potatoes.

Two plates with marinated grilled mushroom steaks, served with broccolini and fries. Table set for two with this vegan recipe.

What is vegan steak made of?

You can find premade vegan steaks in many supermarkets, and they're likely to be a highly processed mixture of soy, seitan, microprotein, vital wheat gluten or other unusual ingredients.

I do eat vegan convenience foods sometimes, but for this vegan steak I wanted it to be natural, plant based and with recognizable ingredients.

I've seen lots of vegan steak recipes with seitan, but my no-seitan vegan steaks are far cheaper, easier to get hold of and less process. 

This vegan steak is made from large flat mushrooms, marinated in a few simple ingredients then grilled (I used a George Foreman-style clamp grill, but you can use a broiler, grill, griddle pan, barbecue, frying pan of oven. 

I've made vegan cauliflower steaks often, but I've found that mushrooms give a better look and texture.

Not that I've ever had an actual meat steak, but to me mushrooms are my favourite vegan steak substitute. 

Mushroom Steak

For these portobello steaks, I've marinaded the large flat mushrooms for a few minutes in a few simple ingredients. 

I've been experimenting with lots of different flavourings in the marinade. Balsamic vinegar is in a lot of mushroom steak recipes, but I found it a bit harsh.

With the below ingredients, I found the perfect steakhouse flavors in a quick and easy marinade.

You don't even need to leave the steaks marinading for long. Just brush them with it and when the grill/griddle pan/oven is hot - then whack them on until soft, juicy and tender. 

Marinade ingredients

Oil - olive, canola, vegetable,whatever you prefer.
Soy Sauce - or tamari for gluten free. 
Onion and garlic powder
Salt and lots of fresh black pepper
Liquid smoke (optional) - You can find it in larger grocery stores in the BBQ sauce section, or online at Amazon (afflink).

Liquid Smoke
Look for the Stubbs or Colgin brands. Use this stuff very sparingly - just a few drops will give a lovely smokey flavour.

If you can't get hold of it, don't worry - the portobello steaks will still be delicious without it.

Follow these simple steps for the perfect Portobello Steaks!

Collage: 1 grilling the mushrooms, 2 flipped, 3 finished.

Heat a grill, griddle pan or George Foreman-style grill.

Add the mushrooms and cook until juicy and tender. If possible, collect the cooking juices to pour over the mushroom steaks on the plate.

How to enjoy Portobello Steaks

I love serving these vegan steaks with fries and green veg, but you could also serve them with mashed potato, wedges, polenta or delicious fried gnocchi.

It's tasty with steamed green veg, but also with turmeric roasted cauliflower.

Equipment

  • Grill pan, griddle, or clamp grill

Ingredients
 

  • 2 Portobello mushrooms (any large flat mushrooms)
  • 3 tablespoons oil
  • 1 teaspoon soy sauce or tamari for gluten free
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • ½ teaspoon ground pepper
  • ½ teaspoon sea salt
  • ⅛ teaspoon liquid smoke optional

Instructions
 

  • Remove the stems from the mushrooms.
  • Add the oil and all seasonings to a large dish and mix. Brush it over the mushrooms, then leave the mushrooms in the remaining liquid to marinade.
  • Heat a griddle pan or clamp grill (like a George Foreman grill). Place the mushroom steaks onto the hot grill and cook until soft and lightly charred. If possible, save the mushroom cooking juices.
  • Alternatively heat a grill/grill pan/bbq/broiler and cook as above. Or, heat the oven to 200c/400f and bake on a tray for 25 minutes or until soft and juicy.
  • Serve with fries or mashed potatoes and steamed broccoli or other veg with the cooking juices poured over the mushrooms.

Notes

If you can't get hold of the liquid smoke (in larger grocery stores and online at Amazon), then these portobello steaks are still lovely without it.

    Simply awesome! Was in the mood for some portobello mushroom steaks and just wasn't feeling the balsamic vinegar marinade that so many other sites have. I used some smoked paprika and cumin in place of the liquid smoke. Pan grilled them for a while and then sliced them thickly and pan grilled each slice a little. We had them with a side of Spanish rice and a corn/pea mix. Best dinner in a long time!

    I grilled these according to your recipe and then chopped the mushrooms into pieces and further cooked them with some onion slices and vegan cheese. I put all that on a fresh baguette with vegan mayo and it made an *amazing* Philly cheesesteak. Thanks for this recipe. It's a keeper!
