If you’re looking for a great meatless, easy weeknight meal that comes together in just about 20 minutes, these Portobello Lettuce Cups are delightful! 

Portobello Mushroom Lettuce Cups

Recently, a lot of you have been requesting more plant-based/vegetarian recipes, which is something I haven’t done as much of in the past! However, I’ve also been trying to cut back a bit on eating meat (although let’s be clear, I very much still consume meat) and mushrooms have become one of my favorite ‘meaty’ veggies to cook with as a replacement! 

In this recipe, the portobello mushrooms soak up a delicious Asian-inspired sauce that is salty, slightly sweet, and a bit spicy. There is also an added crunch from the water chestnuts which I love, and then it is all served inside lettuce cups for a delightful meal or appetizer! Alternatively, you could also serve this over cauliflower rice for a meatless bowl option. No matter how you serve, you will love the flavor!

    This turned out very yummy but my only issue was that the tapioca flour turned kinda gooey after I mixed it with the mushrooms. Is there anything I can do to fix it?

    1. I used arrowroot and the second I poured it into the mushroom mixture, mine turned extremely gooey as well!!

    This dinner was FABULOUS. It was quick and refreshing. I added cauliflower rice. My boyfriend doesn’t eat vegan so I love when he also loves the dinner as much as I do. Thank you for the recipe 🙂

    Oh…… my god? Made for a quick dinner with a side of (TJ’s microwaved) brown rice! I’m an 80% vegan and me and by 0% vegan boyfriend loved this! Definitely filling and impressive flavor with little effort! In the dinner rotation forever (reposted to make sure it got 5 stars!!!)
