Ingredients
- Oil: Optional … Used to sauté the vegetables and build flavor at the start
- Carrots, Onions, Celery: Classic Mirepoix for a flavorful base

Split peas are dried field peas that have been split in half, allowing them to cook faster than most legumes while still providing high levels of fiber, protein, iron, and potassium.
Equipment needed
- Large soup pot or Dutch oven (6–8 quart)
- Cutting board and knife
- Wooden spoon
- Measuring spoons
Prep for the Recipe
- Rinse the split peas under running water and check for debris.
- Clean and chop or slice the mushrooms, carrots, onion, and celery
How to Make Split Pea Mushroom Soup on the Stovetop
Heat oil in a large pot over medium heat. Add carrots, onion, celery, and mushrooms. Sauté 6–8 minutes until the vegetables are softened and fragrant and the mushrooms begin to brown. Add water, split peas, nutritional yeast, miso, smoked paprika, thyme, and bay leaf. Stir well. Bring to a boil, then reduce to a gentle simmer. Simmer uncovered for 60–75 minutes, stirring occasionally. The peas will break down and thicken the soup naturally. Add water if needed. Remove the bay leaf before serving. Taste and adjust salt if needed.
Slow Cooker / Crockpot Instructions 🕒
Add all ingredients directly to the slow cooker. Stir to dissolve the miso paste. Cook on LOW for 8 hours or HIGH for 4–5 hours. Optional: sauté vegetables first for deeper flavor. Remove bay leaf before serving.

Tips & Tricks

Why this fits a healthy Blue Zone-style longevity lifestyle 🌍
Blue Zone regions are known for diets centered on beans, vegetables, whole foods, and simple preparations. Split peas are legumes, one of the most emphasized foods in these longevity-focused cultures.

It’s filling without being rich, satisfying without being heavy, and made from ingredients that support steady energy and digestive health.

Hi, this looks great, thank you. I would like to try it in an instant pot and wonder if you have any idea on timing please?
Hi Sandy, I would do 15 minutes in the instant pot on high-pressure and then let it release for the 10 to 15 minutes and that should give you the same texture as a good long cook on the stove. Let me know how it turns out!
