Bacon Jam Veggie Smash Burger with Portobello Bun

Description

This Bacon Jam Veggie Smash Burger with Portobello Bun reimagines the classic smash burger in a plant-based, low-carb format that's perfect for blood sugar management. The burger patty combines umami-rich mushrooms, walnuts, and sun-dried tomatoes for a meaty texture and savory depth that rivals any beef burger.

The star of this dish is the sugar-free bacon jam—a sweet-savory condiment made with caramelized onions, smoky tempeh bacon, balsamic vinegar, and a touch of monk fruit sweetener. This complex topping adds layers of flavor without the blood sugar impact of traditional bacon jam. Instead of a carb-heavy bun, this burger is served between two roasted portobello mushroom caps that provide a satisfying chew and earthy flavor that complements the fillings perfectly. Topped with sharp cheddar, crisp lettuce, and a tangy special sauce, this burger delivers all the indulgence of fast food with a fraction of the carbs.

Why This Recipe Works

• Mushroom-Based Patty: The combination of mushrooms and walnuts creates a satisfying, meat-like texture with minimal carbs.
• Sugar-Free Bacon Jam: Traditional bacon jam is reimagined without added sugars, using monk fruit sweetener and natural caramelization for sweetness.

• Umami Maximization: Multiple sources of umami—mushrooms, tempeh bacon, sun-dried tomatoes, and aged cheddar—create deep satisfaction without carbs.
• Textural Contrast: The combination of crispy edges on the smashed patty, juicy mushroom buns, and jammy topping creates a dynamic eating experience.

Directions

Prepare the Mushroom-Walnut Patties

1. In a small bowl, mix ground flaxseed with water and let sit for 5 minutes to form a gel.
2. Heat 1 tablespoon olive oil in a large skillet over medium heat. Add chopped mushrooms and cook until they release their moisture and begin to brown, about 5-7 minutes.
3. Add minced garlic and cook for another minute until fragrant.
4. Transfer mushroom mixture to a food processor. Add toasted walnuts, sun-dried tomatoes, flax gel, nutritional yeast, tamari, smoked paprika, thyme, and black pepper.
5. Pulse until the mixture is well combined but still has some texture. It should hold together when pressed.
6. Divide the mixture into 4 equal portions and form into balls. Refrigerate for at least 15 minutes to firm up.

Make the Sugar-Free Bacon Jam

1. Heat 1 tablespoon olive oil in a medium skillet over medium heat.
2. Add chopped tempeh bacon and cook until crispy, about 5 minutes. Remove from skillet and set aside.
3. In the same skillet, add another tablespoon of olive oil and the sliced onions.
4. Reduce heat to medium-low and cook onions, stirring occasionally, until deeply caramelized, about 15-20 minutes.
5. Add minced garlic and cook for 1 minute until fragrant.
6. Return the crispy tempeh bacon to the skillet.
7. Add balsamic vinegar, monk fruit sweetener, tamari, smoked paprika, and water. Stir to combine.
8. Simmer for 5-7 minutes until the liquid has reduced and the mixture is jammy.
9. If using xanthan gum, sprinkle it over the mixture and stir immediately to incorporate and thicken.
10. Remove from heat and let cool slightly. The jam will thicken as it cools.

Prepare the Portobello Buns

1. Preheat oven to 400°F (200°C).
2. Clean portobello caps with a damp paper towel. Remove gills with a spoon if desired.
3. In a small bowl, mix olive oil, garlic powder, salt, and pepper.
4. Brush both sides of each portobello cap with the oil mixture.
5. Place caps gill-side down on a baking sheet lined with parchment paper.
6. Roast for 10-12 minutes until tender but still firm enough to hold as a bun.
7. Remove from oven and let cool slightly.

Make the Special Sauce

1. In a small bowl, combine mayonnaise, sugar-free ketchup, pickle relish, Dijon mustard, smoked paprika, and garlic powder.
2. Stir until well combined and set aside.

Cook the Patties

1. Heat remaining tablespoon of olive oil in a large cast-iron skillet or griddle over medium-high heat.
2. Place the mushroom-walnut balls in the skillet, leaving plenty of space between them.
3. Using a spatula or the bottom of a heavy glass, smash each ball into a thin patty.
4. Cook for 3-4 minutes until the bottom is crispy and browned.
5. Carefully flip and cook for another 2-3 minutes.
6. Place a slice of cheese on each patty during the last minute of cooking to melt.

Assemble the Burgers

1. Place 4 portobello caps gill-side up as the bottom buns.
2. Spread each with a tablespoon of special sauce.
3. Top with a lettuce leaf, then the cheese-covered patty.
4. Add a generous spoonful of bacon jam to each patty.
5. Add tomato and red onion slices if using, and a few pickle slices.
6. Top with remaining portobello caps, gill-side down.
7. Serve immediately.
