Heat one tablespoon of oil in a non-stick skillet over medium heat. Once hot, add the scrambled tempeh and sauté for 3-5 minutes, or until golden brown.
Deglaze the pan with the soy sauce and stir to coat the tempeh. Cook for one more minute. Remove from heat and set aside.
Next, heat another tablespoon of oil and one tablespoon of vegan butter in a medium pot over medium heat. Once the butter has melted, add the onion and garlic, and cook for 2-3 minutes.
Add the diced carrots and celery and sauté for 3-5 minutes. Add the scrambled tempeh and cook for another minute.
Add the diced tomatoes, tomato paste, oregano, rosemary, sugar, and smoked paprika. Pour in the vegetable broth.
Bring to a boil, then lower the heat and let simmer partially covered for 30-40 minutes, or until the bolognese has thickened to your liking. I personally let it simmer for 30 minutes.
Once the bolognese has reached the desired consistency, remove it from heat and adjust the saltiness to taste. Season with about 1/8 tsp of ground black pepper.
Use this bolognese on top of noodles, pasta, or in baked dishes! This bolognese will keep for up to 5 days in the refrigerator.
Notes
If you find your bolognese too chunky: use an immersion blender and pulse a few times until you get a thinner consistency. Do not process for too long as you want to keep some texture.
While optional, you can add about 1/8 tsp of vegan Worcestershire sauce. It will add another level of flavor to the sauce. Highly recommended!
If serving this bolognese on top of pasta: reserve 2-3 tablespoons of the pasta cooking water and stir it into the bolognese. This step will help emulsify the sauce and thicken it.
