Marinated Portobello Burgers with Creamy Pesto Sauce
These are the ultimate Portobello Burgers! Tender portobello mushrooms are marinated, cooked to perfection, and topped with a homemade creamy pesto sauce. Yum.
Remove portobellos stalks. Mix all the ingredients to marinate the portobellos. Using a cooking brush, toss them with the sauce on both sides. Let them marinate for 30 minutes, with the cap side down.
Chop onions in thin slices. Place them in a large skillet with 2 tbsp of olive oil, cook them at medium heat until golden brown.
The onions will need between 25-30 to be caramelized. Stir it regularly; otherwise, it will burn.
Combine all ingredients for the pesto mayonnaise in a blender. Use either a stick blender or a regular blender.
Blend all the ingredients.
Blend until you have a smooth, creamy paste. Adjust salt to taste.
Cook the portobellos cap side down in a heated skillet, grill or BBQ until tender. It will take 8-10 minutes.
To make the burgers, first add pesto mayonnaise to the bread.
Next, add caramelized onions.
Add a juicy portobello.
Top with a slice of tomato and cover with bread. Enjoy!
Notes
Portobellos are my favorite choice when going to BBQs or inviting friends over. They are extremely delicious, juicy and adaptable to any kind of add-on that you can think of. Just get creative by adding different seasonings, vegetables or even some melted cheese.
