This portobello sandwich stars a mix of roasted portobello mushrooms, crunchy veggies, and creamy horseradish sauce. It’s to die for!
Here’s a slam dunk for mushroom lovers, or anyone looking for a meaty vegetarian sandwich. Try this Portobello Sandwich! It’s modeled after a steak sandwich, but instead the filling is juicy roasted portobello mushrooms, seasoned with garlic, soy sauce and smoked paprika. Add to that crunchy pickles and onions, and the kicker: a horseradish sauce that smothers it all with a creamy, spicy tang. You’ll become a believer after your first bite!
What’s in this portobello sandwich?
You can build a portobello sandwich with many different flavor profiles. In fact, a Portobello Burger is a prime example of a classic spin on one. For this one, we took inspiration from a steak sandwich, infusing the roasted portobello mushrooms with smoky, savory spices and topping it off with a horseradish sauce. Here’s what you’ll need for this recipe:
- Portobello mushrooms
- Olive oil
- Soy sauce (or tamari)
- Garlic
- Smoked paprika, onion powder and salt
- Worcestershire sauce
- Artisan buns
- Baby arugula or greens, pickles, and white onion , for serving
- Horseradish sauce, for serving
How to make roasted portobello mushrooms
The filling for this sandwich is not a whole portobello mushroom like in a Portobello Burger, but sliced mushrooms. The advantages? The sandwich is much easier to eat than trying to pull bites off of a big juicy portobello. It also makes for a taller sandwich, which is more aesthetically pleasing and has more mushroom flavor. Here’s the basic idea around how to make roasted portobello mushrooms:
- Preheat the oven to 450 degrees Fahrenheit. Mushrooms roast best at very high heat.
- Slice the portobello caps into 1/4-inch thick slices and season. Add olive oil and spices. We’ve found the combination of soy sauce, Worcestershire, garlic and smoked paprika makes an intensely savory, meaty flavor.
- Roast for 15 minutes. That’s it! The mushrooms come out juicy and tender.
Don’t skip the sauce
This portobello sandwich highlights mushrooms, of course. But the other star who’s vying for attention? The horseradish sauce! This sauce is so full of creamy, savory flavor, it almost steals the show. Look for prepared horseradish in the condiments section of your local grocery, then you’ll need sour cream, mayo, Dijon mustard, vinegar, and chives. It’s simple and lasts for 2 weeks, and you can use it on just about anything: a fries dip, salads, and more.
Ways to serve this portobello sandwich
One thing to note about this portobello sandwich: because it’s based around mushrooms, it doesn’t have lots of protein. So when you serve this sandwich, make sure to serve with other proteins to make it into a complete meal. Here are some ideas:
- Beans like Classic Three Bean Salad or Easy White Bean Salad
- Lentils like Lentil Salad with Feta or French Lentil Salad
- Salads like Kale Caesar Salad, Simple Chickpea Salad or Simple Radish Salad
