Whether you’re hosting a BBQ gathering or simply craving a delicious and satisfying meal, this grilled oyster mushrooms recipe is an absolute winner.
Ingredients & Substitutions
First, we have oyster mushrooms, which are the stars of the dish. These mushrooms bring a unique flavor and a meaty texture that work wonderfully in this recipe. If you can’t find oyster mushrooms, don’t worry! You can try using shiitake or portobello mushrooms as alternatives for a similar result.
Next, we have harissa paste, which adds a delightful kick of spiciness. If you prefer a milder flavor, simply reduce the amount of harissa paste or substitute it with a milder chili paste that suits your taste.
Agave is used to provide a touch of sweetness to the marinade. However, if you prefer, you can easily swap it out with honey or maple syrup, depending on your personal preference.
When it comes to the marinade, tomato paste is essential for adding depth and richness. In case you don’t have any on hand, worry not! You can substitute it with tomato sauce or even ketchup to still achieve a delicious result.
For a refreshing tanginess, lemon juice is a key ingredient. However, if lemons are not available, feel free to use lime juice as a great alternative.
To enhance the flavors, we have smoked paprika and garlic powder. Adjust the quantities according to your taste preferences, or if you’re not a fan of these flavors, simply omit them from the recipe.
Coating the mushrooms and enhancing their taste, we use extra virgin olive oil. If you prefer, you can explore using other oils like avocado oil or vegetable oil to achieve a different flavor profile.
Lastly, don’t forget to season the dish with salt and pepper. Adjust the amounts according to your liking for that perfect balance of flavors.
Helpful Tools

How to Make Grilled Oyster Mushrooms with Harissa
Start by wiping the oyster mushrooms clean with a damp paper towel to remove any dirt or debris.
In a large mixing bowl, combine the harissa paste, agave (or substitute), tomato paste, lemon juice, olive oil, smoked paprika, garlic powder, salt, and pepper to create a delicious marinade.

Tear the oyster mushrooms into large, bite-sized pieces and gently toss them in the marinade to ensure they’re well coated.

Preheat the grill to around 375 degrees, and skewer the marinated oyster mushrooms, leaving a little space between each piece for even grilling.

Grill the mushrooms for approximately 5-7 minutes per side, or until they shrink and achieve your desired level of char. Brush any remaining marinade onto them for an extra burst of flavor.

While the mushrooms are grilling, grill the flatbread for 1-2 minutes until warm and slightly toasted.

Spread the homemade garlic aioli onto the grilled flatbread, then add a generous handful of arugula or spinach on top.

Finally, place the cooked harissa oyster mushrooms on the greens, and it’s time to enjoy these scrumptious wraps!
Tips & Tricks
- Marinating the Mushrooms: For an even more intense flavor, marinate the oyster mushrooms for 30 minutes to an hour before grilling. This allows the flavors to penetrate the mushrooms more deeply.
- Perfect Grilling: To achieve those beautiful grill marks on the oyster mushrooms, make sure the grill is preheated to the recommended temperature. Additionally, don’t overcrowd the grill, as it can lead to uneven cooking. Give each mushroom piece enough space to cook properly.
- Adjust the Spices: Feel free to experiment with the spice levels by adjusting the quantities of harissa paste, smoked paprika, and garlic powder. Add a bit more if you love bold flavors or reduce them slightly for a milder taste.
- Creative Wrapping: While garlic naan is a great choice for these wraps, you can explore other types of flatbread as well. Try whole wheat tortillas, pita bread, or even lettuce wraps for a lighter option.
- Double the Recipe: This recipe is fantastic for gatherings, so consider doubling or tripling the ingredients to feed a larger group. You can even set up a “build-your-own” wrap station where everyone can assemble their personalized wraps with their favorite toppings.
