Let’s be completely honest, dear friends and fellow food enthusiasts. The majestic stack you see pictured above – a towering masterpiece of flavor and texture – wasn’t quite devoured sandwich-style, held delicately in two hands.

In fact, quite the opposite! Only the most truly epic, awe-inspiring burgers necessitate such refined dining tools.

Crafting the Perfect Plant-Based Burger: What You Need for Tempeh Burgers with Portobello Mushroom Buns

This innovative, plant-based, grain-free, and gluten-free take on the beloved classic American burger naturally begins with an outstanding, flavorful plant-based patty. For this recipe, we turn to tempeh – a fantastic fermented soybean product that serves as an exceptional “burger” base. Tempeh is not only rich in protein and fiber, making these burgers incredibly satisfying, but its inherent density and firm texture mean it’s already perfectly compressed and ready to be sliced into burger form straight out of the package. This eliminates the need for extensive binding or shaping, simplifying your cooking process considerably.

Our tempeh patties are actually designed as square shapes, easily achieved by halving a standard tempeh block. This unique shape isn’t just for aesthetics; it provides even more surface area for that delicious, savory char when grilled. This makes it an ideal canvas for soaking up marinades and developing a deep, complex flavor profile that will impress even the most discerning burger connoisseurs. Beyond the tempeh itself, you’ll need a handful of pantry staples for the marinade, ensuring each bite is bursting with taste. And for our innovative buns, fresh portobello mushroom caps are key, providing a wholesome, sturdy, and naturally gluten-free alternative to traditional bread.

How to Make Flavorful Marinaded Tempeh Burgers

The secret to these incredibly “juicy” and satisfying tempeh burgers lies in a tangy, homemade marinade. While tempeh is wonderfully absorbent, giving it time to soak in a flavorful liquid infusion is crucial for transforming it from a relatively mild block into a deeply savory, umami-rich patty. My preferred method involves preparing the marinade in the late afternoon, allowing the tempeh to luxuriate and fully absorb all those vibrant flavors for a few hours. Then, as dinnertime approaches, the perfectly marinated tempeh is ready to hit the grill.

The beauty of this recipe is its flexibility. While longer marination (up to 4 hours or even overnight) undoubtedly yields the most intensely flavored burgers, I’ve found that even an “express” 30-minute soak can produce remarkably tasty results if you’re short on time. The marinade typically includes a balance of savory (like tamari or soy sauce), acidic (such as white wine vinegar and fresh lemon juice), and aromatic components (like garlic powder and fresh thyme). Each ingredient plays a vital role: the tamari provides depth and saltiness, the vinegar and lemon juice tenderize the tempeh and add brightness, and the herbs infuse it with a fragrant, earthy essence. Don’t be afraid to experiment with other herbs like rosemary or oregano, or add a touch of smoked paprika for an extra layer of flavor. The goal is to create a tempeh patty that’s not just plant-based but bursting with character and deliciousness. This marinating process ensures your tempeh burgers are tender, flavorful, and incredibly satisfying, perfect for your next vegan BBQ.

Mastering the Art of Portobello Mushroom Buns

Preparing the portobello mushroom buns is surprisingly simple and requires minimal fuss, as these naturally meaty mushrooms are inherently delicious and don’t need extensive marinating to shine. Their substantial size and robust texture make them an ideal, low-carb, and gluten-free alternative to traditional burger buns. With just a touch of avocado oil, a sprinkle of salt and pepper, and some time on a hot grill pan, these humble fungi transform into juicy, tender “steaks” – perfect for cradling your tempeh patties.

My intention for these portobello buns was to maintain a more natural, earthy flavor profile. This allows the intensely flavored tempeh, with its rich marinade, to be the star of the show. However, if you’re seeking an extra burst of flavor and wish to elevate your mushroom buns even further, don’t hesitate to give them a quick marinade as well! A simple marinade of balsamic vinegar, a dash of garlic powder, and a hint of fresh herbs could add another layer of deliciousness. When preparing them, remember to gently clean the caps, carefully remove the stems, and scoop out the dark gills to prevent them from becoming overly watery and to create a cleaner “bun” surface. Grilling them cap-side down initially helps to tenderize them and achieve beautiful grill marks, making them not only tasty but visually appealing. This simple preparation ensures your portobello mushroom buns are the perfect wholesome foundation for your healthy tempeh burgers.

Serving Your Tempeh Burgers with Portobello Mushroom Buns: Perfect for Any Occasion

Whenever we gather for a summer grill-out with Dan’s family, my father-in-law often good-naturedly jokes about tossing a lone zucchini onto the grill alongside their usual fare, quipping, “For a light dinner, eh?” Next time, I’ll be armed and ready with these exquisitely marinaded tempeh burgers, prepared and waiting to demonstrate just how satisfying and truly delicious a plant-based, gluten-free grilled meal can be. These burgers aren’t just an alternative; they are a destination meal unto themselves, worthy of any barbecue spread.

These tempeh burgers with portobello mushroom buns are fantastic for a quick and easy summer lunch, a wholesome weeknight dinner, or a vibrant contribution to a potluck. They’re designed for sharing – or, if you’re like me and appreciate a good meal prep strategy, keep the leftovers all to yourself! Store the individual “burger” patties and “buns” separately in the fridge for 2-3 days. When hunger strikes again, simply reassemble and gently reheat, and you’ll have a fresh stack of deliciousness ready to enjoy all over again. Their versatility extends beyond just the patty and bun; they pair wonderfully with a variety of sides, from a crisp green salad to grilled corn on the cob, or even a hearty serving of sweet potato fries. These burgers are more than just a recipe; they’re an invitation to embrace joyful, healthy eating that everyone at your table can enjoy.

Elevate Your Meal: Creative Toppings for Tempeh Burgers

One of the most enjoyable aspects of any burger experience is customizing it with an array of delectable toppings. These tempeh burgers are no exception; they serve as the perfect canvas for your favorite additions, allowing you to stack them high and create your ultimate personalized meal. For my personal stack, I chose a vibrant combination of fresh, crisp kale, juicy heirloom tomato slices, thinly sliced red onion for a zesty bite, creamy avocado for richness, and a classic dollop of tangy yellow mustard.

But the possibilities are truly endless! Consider these additional topping ideas to spark your creativity and cater to diverse palates:

  • Classic Condiments: Beyond mustard, don’t forget ketchup (a must for many!), a smoky BBQ sauce, or a spicy sriracha mayo for a kick.
  • Creamy & Cheesy: Add a slice of your favorite plant-based cheese, a generous spoonful of hummus, or a dairy-free aioli for extra creaminess. A cashew cream sauce could also be a luxurious addition.
  • Crunchy & Tangy: Try sauerkraut or kimchi for probiotics and a delightful tang, crisp pickles or cucumber slices, or even some crunchy onion rings (baked or air-fried for a healthier twist).
  • Fresh & Flavorful: Beyond tomato and kale, consider fresh spinach, thinly sliced bell peppers, grilled pineapple for a sweet and savory contrast, or a vibrant pico de gallo.
  • Herbs & Spices: A sprinkle of fresh cilantro, a dash of red pepper flakes, or a squeeze of fresh lime juice can brighten up the entire burger.

For the perfectly appropriate veg pairing that complements these delightful burgers, I highly recommend serving them alongside my Oil-Free Baked Yam Fries. The natural sweetness of the yam fries provides a wonderful counterpoint to the savory tempeh and earthy portobello. It’s a truly satisfying and wholesome combination. Yum!

Enjoy building your masterpiece and savoring every single bite!

Description

Marinaded tempeh burgers served between portobello mushroom buns with classic toppings. The perfect gluten-free and vegan alternative for summer grilling!


Ingredients

Tempeh Burgers

  • 8 oz. tempeh
  • 1 TBSP tamari lite
  • 1/2 tsp garlic powder
  • 1 cup veggie broth (or enough to cover tempeh in marinade)
  • 2 TBSP white wine vinegar
  • 3 TBSP fresh lemon juice
  • 12 TBSP fresh thyme leaves (or sub 12 tsp dried thyme)

Portobello Mushroom Buns

  • 4 portobello mushroom caps, stem and gills removed
  • Himalayan sea salt, to tastw
  • Black pepper, to taste
  • 12 tsp avocado oil

Burger Toppings

  • greens
  • sliced tomato
  • sliced onion
  • sliced avocado
  • mustard
  • ketchup
  • anything else!


Instructions

  1. Slice the tempeh rectangle into two squares to create your tempeh “burgers”. Mix all of the marinade ingredients together in a glass dish, then transfer the tempeh into the marinade. Allow the tempeh to marinade for 1 to 4 hours, flipping occasionally.
  2. Meanwhile, prepare your portobello mushrooms. To clean, lightly dust the cap with a damp rag. Flip the mushrooms over and saw off the stem with a knife so that it’s flush to the cap. Remove the gills by scraping the inside out with a spoon. Set aside. Rub the portobello mushrooms with a bit of avocado oil and season with Himalayan sea salt and pepper.
  3. Preheat a grill-pan over medium high with a bit of avocado oil. Once the pan is warm, add the portobello mushrooms cap sided down. Cook them for 10 minutes total, flipping halfway, until the mushrooms are tender and flattened with visible grill marks. Remove them from the grill pan and set them aside.
  4. Next, grill your tempeh. Lightly oiled the same grill-pan over medium high ((I used a grill pan but you could do this outdoors, too!) Cook the tempeh for 5-7 minutes on each side, until you see dark brown grill marks on both sides. If the pan starts to look dry, I like to add spoonfuls of the marinade as it cooks to moisten the tempeh and enhance the flavor.
  5. To serve, sandwich a tempeh burger inside of the portobello mushroom caps and top them with your favorite burger toppings. I chose kale, tomato, onion, avocado, and mustard.
  6. Store leftover “burger” and “buns” separately in the refrigerator for 2-3 days and reassemble and reheat before serving.
