BBQ Portobello Sliders

Summer makes me happy… long sunny days, warm nights, flip flops, juicy watermelons, waffle cones, and food with ketchup. Or in this case, BBQ sauce.

A few weeks ago, I was drooling over this post. So last weekend, for my dad and Jack, I decided to made a mushroom version. The only change I really made to the sauce was adding dijon mustard. I love ketchup… Jack hates it… so the mustard added a nice kick and kept the overall tomato-y factor in balance.

Author: Jeanine Donofrio
Serves: makes about 6 sliders
Ingredients
  • 4 portobello mushroom caps
  • buns of your choice
  • fixings of your choice: (sprouts, onion, tomato avocado, blue cheese, etc)
for the sauce:
  • 1 teaspoon olive oil
  • ¼ onion, grated
  • 1 clove of garlic, minced
  • ¾ cup ketchup
  • 2 tablespoons dijon mustard
  • 2 tablespoons apple cider vinegar
  • 2 tablespoons maple syrup
  • 1 tablespoon worcestershire (I use the vegan brand)
  • ½ to 1 teaspoon sriracha or hot sauce
  • salt and pepper, to taste
Instructions
  1. Make the sauce. In a small saucepan, heat oil. Add onion and garlic. Stir until translucent. Stir in the rest of the ingredients. If the mixure is not already bubbling, increase heat. As soon as it bubbles, reduce to a simmer. Let it reduce and thicken (5-10 minutes), stirring occasionally. Taste and adjust seasonings to your liking - sweetness, spice level, salt, etc.
  2. Depending on the size of your portobello's, either trim to fit the size of your slider bun, or cut into strips. (To make slider-sized burgers and not waste mushroom scraps, I made some of both - cut squares like the one pictured, and made others with mushroom strips).
  3. Liberally brush both sides of the mushrooms with the sauce and let them marinade for at least 15 minutes, up to 30.
  4. Heat broiler or grill, cook mushrooms, flipping halfway through. (the time will completely depend on the heat of your broiler or grill). Grill should be a few minutes per side, I broiled mine in the oven for about 3-5 minutes per side. I have a really hot broiler.
  5. When mushrooms are done cooking, brush with more sauce and serve with whatever fixings you like.

    I made these for my meat-eating boyfriend and we both really loved them! It was not hard to make and was really delicious! We cut them into strips and put them in ciabatta buns. I would definitely make these again!

    These look absolutely delicious! I’ve had portobello many times, but never with BBQ sauce. I don’t know why I never thought it. These are going on my list to make this summer!

    Okay – we’ve been eating portobello mushroom burgers (or just stacked w/ grilled eggplant) all week and not once did it occur to me to make it BBQ style. Yowza, I am so excited about this!

    Lovely slides, I would eat one! Mushrooms are my “meat”, but I rarely use it on burgers, well, I rarely make/or eat burgers, not my thing.

    Nice recipe! I’ve seen this variation many times now, but I always somehow forget to try it… ^_^
    What I like about summer? The strong light and to be able to see the blue of the sky… ^_^

    My favorite thing about summer is the Outdoors. Eating outdoors. Reading outdoors. Drinking my morning tea and journaling outdoors. There is just something magical about summer mornings and nights–

    This look so fabulous. I love using mushrooms as a “burger” instead of veggie patties sometimes. Yum!
