Juicy marinated mushrooms meld together with peppers, onions & mozzarella cheese. Basil mayonnaise finishes off this Portobello Mushroom Burger perfectly.
When I first got on IG I started something I hashtagged #MittenMovieNight. Usually, Friday nights hubby & I enjoy a few craft beers and watch a movie. I snapped what we are drinking and watching and tag it with this hashtag. I look forward to this fun little night and I also look forward to sharing it. So I thought, hey why not add a recipe to go along with it. YEAH! Dinner, Movie, Craft Beer! So that is how #MittenMovieNight was born.
Here is just a taste of some of my FAVORITE recipe & beer pairings:
What to watch while eating a juicy mushroom burger?
For this Mitten Movie Night we’re watching, The Bronze
What should I drink with a Marinated Portobello Mushroom Burger?
The beer: Boom Boom Betty from Three Blondes Brewing
Blondes are my favorite type of beer. Subtle with a nice fruity flavor and everyone I try is different from the other. But what I do know is that I will never go wrong. It’s delicious.
How to make Portobello Mushroom Burgers in the oven:
Start with the Basil Mayonnaise. In a food processor combine basil, garlic, and salt. While running add oil through the top and blend until smooth.
Take the ingredients from the processor and move to another bowl. Add the rest of the ingredients and stir until combined. Cover and refrigerate. This will keep for around 3 days. *Pro-tip: Basil mayo is also great on sandwiches!
Next, mix the marinade ingredients together for mushrooms. Oil, vinegar, salt and lemon juice. Set aside.
Prepare the mushrooms by removing the stems and scraping the gills out. Don’t miss this step since leaving the gills in the mushroom can make them release more water, therefore, making them soggy.
Place mushrooms in a dish and pour the marinade over them. Let it sit in the marinade at room temperature for 10 minutes.
While the mushrooms marinate, chop peppers and onion.
Add 2 Tbs. of butter in a pan, let it melt over medium/high heat then add the peppers and onions to the pan. Sautee for 5 minutes.
Assemble the marinated mushrooms on a greased baking pan. With mushroom cup side up add onions and peppers. Top with mozzarella cheese.
Bake at 425 degrees for 20-22 minutes.
In the last 5 minutes of cooking the mushrooms, I put butter on my split rolls and put them in the oven as well to crisp up the buns.
Smear the rolls of your choosing with pesto mayo. Add mushroom burger. And here you are…..
From our home in the Bottom Left of the Mitten to yours ~ Enjoy!
