This vegan mushroom bacon is smoky, savory, slightly sweet, and crisp around the edges with a chewy center. Instead of relying on one mushroom and a heavy marinade, this recipe combines meaty king oyster mushrooms with shiitake mushrooms, then finishes them with a maple-miso glaze for deeper umami flavor.
The important trick is simple: cook the mushrooms before adding most of the glaze. This allows excess moisture to escape first, so the final coating can caramelize instead of steaming the mushrooms.
Why This Vegan Mushroom Bacon Works
- Deep smoky flavor: Smoked paprika and a small amount of liquid smoke give the mushrooms a bacon-style smoky character.
- Better umami: White miso and soy sauce add savory depth without making the mushrooms taste overly salty.
- Crispy edges: The mushrooms are roasted before the glaze is added, helping them lose excess moisture.
- Chewy center: King oyster mushrooms provide a substantial texture that works well in sandwiches and breakfast dishes.
- Caramelized finish: Maple syrup creates lightly browned, sticky edges during the final roast.
- Versatile: Use it for breakfast, vegan BLTs, avocado toast, salads, pasta, baked potatoes, or grain bowls.

How to Make Vegan Mushroom Bacon
1. Prepare the Mushrooms
Heat the oven to 400°F (200°C). Line a large baking sheet with parchment paper and place a wire rack over the sheet if you have one.
Wipe the mushrooms clean with a damp paper towel. Avoid soaking them in water because excess surface moisture makes it harder to achieve crisp edges.
Trim the ends from the king oyster mushrooms. Using a sharp knife, slice the stems lengthwise into thin strips, about 1/8 to 1/4 inch thick.
Thinly slice the shiitake caps.
2. Season Before the Glaze
Place the mushrooms in a bowl and toss gently with the olive oil, salt and black pepper.
Spread them in a single layer on the prepared baking sheet.
Do not pile the mushrooms on top of each other. Space between the pieces allows moisture to escape and helps the edges brown.
3. Roast to Remove Moisture
Roast the mushrooms for about 12–15 minutes.
Remove the tray and carefully turn the mushroom strips.
At this stage, they should already look noticeably smaller and slightly browned around the edges.
Do not worry if they are not crispy yet. The first stage is mainly about removing moisture and developing a roasted mushroom flavor.
4. Make the Smoky Maple Miso Glaze
While the mushrooms roast, whisk together the soy sauce or tamari, maple syrup, white miso, smoked paprika, garlic powder, onion powder, liquid smoke, apple cider vinegar and nutritional yeast.
Whisk until the miso is completely dissolved and the mixture looks smooth.
5. Add the Glaze
Transfer the roasted mushrooms to a bowl.
Add the glaze and gently toss until every piece is lightly coated.
Do not let the mushrooms sit in the glaze for a long time. A thin coating is enough to provide flavor without adding too much moisture.
6. Roast Until Caramelized
Return the mushrooms to the baking sheet and arrange them in a single layer again.
Return them to the oven for another 8–12 minutes, watching carefully during the final few minutes.
The edges should become darker and caramelized while the thinner pieces become crisp.
If some pieces are already dark while others still need time, remove the darker pieces and continue roasting the rest.
7. Let the Mushroom Bacon Cool
Remove the tray from the oven and allow the mushrooms to cool for 3–5 minutes.
This matters because the edges become firmer as the mushrooms cool.
Finish with a tiny pinch of flaky sea salt or freshly cracked black pepper if desired.
The Secret to Crispy Mushroom Bacon
The biggest enemy of crispy mushroom bacon is water.
Mushrooms naturally release a large amount of moisture as they cook. If you crowd the pan or cover the mushrooms with a heavy wet marinade from the beginning, they are more likely to steam than crisp.
That is why this recipe uses a two-stage cooking method:
- Roast the mushrooms first to remove moisture.
- Add the concentrated glaze.
- Roast again until the glaze caramelizes.
This gives you better control over both texture and flavor.
Why King Oyster Mushrooms Work So Well
King oyster mushrooms have thick, firm stems that can be sliced into long strips. They stay more substantial after roasting than very thin mushrooms and give the finished bacon a satisfying chewy center.
Shiitake mushrooms are added for their strong natural umami flavor. They become smaller and crispier than the king oyster strips, giving the finished batch a mixture of textures.
Do Not Cut the Mushrooms Too Thin
Extremely thin mushroom slices can become brittle or burn quickly, especially during the second roasting stage.
A slice around 1/8 to 1/4 inch thick gives you a better balance between crisp edges and a slightly chewy center.
How to Avoid Salty Mushroom Bacon
Soy sauce, miso and salt all contribute sodium, so you do not need a heavily salted marinade.
Start with the recommended amount and taste the finished mushrooms after roasting. Add flaky salt only at the end if necessary.
How Much Liquid Smoke Should You Use?
Liquid smoke is extremely concentrated. A small amount is enough to add a noticeable smoky flavor.
Start with 1/4 teaspoon. If you want a stronger smoky flavor, add another small amount the next time you make the recipe.
Using too much liquid smoke can overpower the mushrooms and make the finished bacon taste artificial.
Easy Variations
Extra Crispy Mushroom Bacon
Slice the mushrooms slightly thinner and use a wire rack over the baking sheet. This allows hot air to circulate around more of the mushroom surface.
Spicy Mushroom Bacon
Add 1/8–1/4 teaspoon cayenne pepper or a pinch of red pepper flakes to the glaze.
Maple Pepper Mushroom Bacon
Increase the freshly cracked black pepper and add another teaspoon of maple syrup for a sweeter breakfast-style flavor.
Gluten-Free Mushroom Bacon
Use certified gluten-free tamari instead of regular soy sauce and check the labels of your miso and other seasonings.
Extra Smoky Mushroom Bacon
Add a small pinch of smoked salt instead of increasing the liquid smoke. This gives you additional smoky flavor without making the glaze overly wet.
Best Ways to Use Vegan Mushroom Bacon
Vegan BLT
Layer the crispy mushroom bacon with lettuce, tomato and vegan mayonnaise between toasted bread.
Breakfast Sandwich
Add mushroom bacon to a toasted English muffin with avocado and tofu scramble.
Avocado Toast
Top toasted sourdough with mashed avocado, mushroom bacon, lemon juice and cracked black pepper.
Salads
Use the crispy pieces as a smoky topping for green salads, Caesar-style salads or grain bowls.
Pasta
Scatter the mushroom bacon over creamy vegan pasta just before serving so it stays crisp.
Baked Potatoes
Add it to baked potatoes with vegan sour cream, chives and a little nutritional yeast.
Can You Make Mushroom Bacon in an Air Fryer?
Yes. Arrange the prepared mushrooms in a single layer in the air-fryer basket.
Cook at approximately 375°F (190°C), checking frequently because the thin pieces can brown quickly.
For the best result, cook the mushrooms briefly before adding the glaze, then return them to the air fryer for the final caramelization stage.
Can You Make Mushroom Bacon in a Skillet?
Yes, although the oven method gives you more even drying.
For a skillet method, use a large pan and cook the mushrooms in batches. Crowding the pan traps steam and prevents browning.
Add the glaze only after the mushrooms have browned and most of their moisture has cooked away.
Storage
Allow the mushroom bacon to cool completely before storing.
Place it in an airtight container and refrigerate for up to 4 days.
For the best texture, reheat it in an air fryer, toaster oven or dry skillet rather than the microwave.
How to Reheat Mushroom Bacon
Heat the mushrooms in a 375°F (190°C) oven or air fryer for a few minutes until hot and crisp again.
A microwave will warm the mushrooms quickly but can make them softer, so it is not the best option when crispness matters.
Can You Freeze Mushroom Bacon?
You can freeze it, but the texture is best when freshly cooked or refrigerated.
If freezing, cool the mushroom bacon completely and freeze it in a single layer before transferring it to a freezer-safe container.
Reheat directly from frozen in an oven or air fryer until hot and crisp.
Frequently Asked Questions
Is mushroom bacon really vegan?
Yes. This recipe uses mushrooms, plant-based seasonings and maple syrup instead of animal products. Check the labels of your miso, soy sauce and other ingredients if you need to avoid specific allergens.
What mushrooms are best for vegan bacon?
King oyster mushrooms are excellent for long strips because their firm stems hold their shape. Shiitake mushrooms add strong umami flavor and become crisp around the edges.
Can I use portobello mushrooms?
Yes. Portobello can be sliced into strips and roasted using the same general method, although its texture will be different from king oyster mushrooms.
Why is my mushroom bacon soggy?
The most common reasons are overcrowding the baking sheet, using mushrooms that are too wet, or adding too much marinade before the mushrooms have released their moisture.
Why did my mushroom bacon burn?
The maple syrup in the glaze can caramelize quickly. Watch the mushrooms closely during the final roasting stage and remove thinner pieces if they become dark before the thicker pieces are ready.
Can I make this without liquid smoke?
Yes. The smoked paprika and roasted mushrooms will still provide a smoky, savory flavor. The result simply will not have as pronounced a smoke flavor.
Can I use maple syrup instead of brown sugar?
Yes. Maple syrup works especially well because it adds sweetness and helps the glaze caramelize around the mushroom edges.
Common Mistakes to Avoid
- Crowding the pan: Use a second baking sheet if necessary.
- Soaking the mushrooms: Wipe them clean instead of leaving them waterlogged.
- Adding the glaze too early: Roast the mushrooms first so they can release moisture.
- Using too much liquid smoke: Start small because the flavor is concentrated.
- Skipping the cooling step: The mushroom edges become firmer as they cool.
- Overbaking thin slices: Check frequently during the final minutes.
Final Tips for the Best Vegan Mushroom Bacon
- Choose firm mushrooms for better texture.
- Slice the king oyster mushrooms evenly.
- Keep the first roasting stage relatively dry.
- Use a single layer on the baking sheet.
- Add the smoky maple miso glaze after the mushrooms have started browning.
- Do not overdo the liquid smoke.
- Watch closely during the final caramelization.
- Let the finished mushrooms cool for a few minutes before serving.
- Use an oven or air fryer to re-crisp leftovers.
Final Thoughts
This crispy vegan mushroom bacon is smoky, savory, lightly sweet and packed with umami. The combination of king oyster mushrooms and shiitake gives you two textures, while the maple-miso glaze adds a deeper flavor than a basic soy-and-smoked-paprika marinade.
Serve it for breakfast, tuck it into a vegan BLT, scatter it over avocado toast, or use it anywhere you want a smoky, crispy plant-based topping.
