Ingredients & Substitutions

- Mushroom broth: Provides depth and umami flavor to the cooked oat bran. Vegetable broth works as a substitute, though the mushroom flavor will be milder.
- Baby Bella mushrooms: Sliced and sautéed, they bring richness and earthy flavor to mushroom oat bran. Other varieties like cremini or shiitake can be used for a different flavor profile.
- Soy sauce: Adds a savory boost and balances the mushrooms in this mushroom oatmeal. Use tamari for gluten-free or coconut aminos if avoiding soy.
- Black pepper: Freshly ground black pepper adds warmth and subtle spice. You can adjust the amount to taste or add smoked paprika for a different twist.

Step-By-Step Recipe
- Sauté the mushrooms: Heat a non-stick pan over medium-high heat and cook the sliced mushrooms until golden on both sides. Season with black pepper while cooking. Remove from the pan and set aside for topping.
- Cook the oat bran: In a small pot, combine oat bran and mushroom broth. Bring to a boil, then reduce heat to a simmer. Stir frequently for 1-3 minutes until the mixture thickens and becomes creamy.
- Assemble the bowls: Pour the cooked oat bran into bowls. Top with the sautéed mushrooms and a splash of soy sauce. Serve immediately while warm and enjoy the savory flavors.
Tips for the Best Mushroom Oat Bran
- Don’t leave the oat bran unattended: Cooked oat bran thickens very quickly, so frequent stirring is key. Staying nearby prevents clumps and ensures a smooth, creamy texture. It also helps incorporate the flavors evenly.
- Use a variety of mushrooms: Baby Bella mushrooms are rich and earthy, but mixing in shiitake or cremini adds depth. Different mushrooms bring slightly different textures and flavors. This makes mushroom oat bran more interesting and flavorful.
- Enhance the umami: Adding mushroom bouillon powder or extra soy sauce can deepen the savory flavor. This trick works especially well if your mushrooms are milder varieties. It creates a more satisfying, rich bowl of mushroom oatmeal.
What to Serve with Mushroom Oat Bran
Mushroom oat bran pairs beautifully with air fryer tempeh bacon, scrambled tofu, or roasted potatoes. For a dinner twist, serve it with sweet plantains or a simple vegetable sauté. Light salads like cucumbers, tomatoes, and red onion dressed with lemon and olive oil also complement the creamy, savory mushroom oats.
How to Store Mushroom Oat Bran
Mushroom oat bran is best enjoyed fresh and warm for the creamiest texture and richest flavor. If you have leftovers, store them in an airtight container in the fridge for up to three days. It also freezes well; portion into freezer-safe containers and store for up to three months. Reheat gently on the stovetop or in the microwave, adding a splash of plant milk or broth to loosen the texture if needed.
