Ingredients You’ll Need

250 grams mushrooms sliced. Any variety you like.
4 medium potatoes around 450 grams peeled and cubed. Starchier varieties give a thicker soup.
1 medium brown onion finely chopped. Tears are allowed.
2 cloves garlic minced. Use more if you are bold.
2 stalks green onion finely chopped for freshness and garnish.
1 teaspoon mixed Italian seasoning because herbs are friends.
1 quarter teaspoon red pepper flakes for a tiny kick. Skip if you do not like heat.
1 quarter teaspoon ground black pepper. Freshly ground if you can.
Salt to taste. Start small and add more later.
2 cups vegetable stock. Use low sodium if you want control.
1 cup any plant based milk. Almond, oat, soy all work.
2 tablespoons olive oil. One to sauté and one for round two.

Step-by-Step Instructions

Heat 1 tablespoon of olive oil in a large cooking pot. Add sliced mushrooms and sauté on medium heat for 4 to 5 minutes or until they are almost cooked and release moisture. Transfer the sautéed mushrooms along with the juices released by them to a bowl. Keep the mushrooms aside.
Heat the remaining 1 tablespoon of olive oil and add chopped onion. Sauté until the onion becomes translucent. Watch so it does not brown too much.
Add minced garlic and sauté for a few seconds until its raw smell goes away. Garlic cooks fast so do not wander off.
Add Italian seasoning and chili flakes. Sauté for around 30 seconds to bloom the flavors. Smell check here. It should start smelling nice.
Add chopped potatoes, salt, and ground black pepper. Sauté for a minute. Add a splash of water if the seasonings start sticking to the pot. Stir so nothing burns.
Add vegetable stock and mix. Cook covered for around 25 to 30 minutes or until the potatoes are nicely cooked. Peek once or twice but leave the lid mostly on.
Remove the lid and roughly mash half of the potato cubes with a masher or the back side of a ladle. This thickens the soup while keeping some texture.
Add sautéed mushrooms, milk, and chopped green onion. Mix everything and cook for another 4 to 5 minutes so the flavors marry and the soup heats through. Keep it at a gentle simmer.
Turn off the heat and garnish with more chopped green onion. Taste and adjust salt and pepper. Serve hot.

Common Mistakes to Avoid

Thinking more heat means more flavor. Too high heat ruins mushrooms and fries garlic into bitterness. Keep it medium.
Overmashing everything until it is baby food. You want some chunks for texture. Rough mash half the potatoes only.
Forgetting to season in stages. Add a pinch of salt at the potato stage and check again at the end. It is easier to add than take away.
Dumping straight milk into a roaring boil. Warm it slightly first or reduce heat to avoid curdling.
Skipping the mushroom juices. Seriously, those juices are flavor gold. Do not toss them.
Using watery non creamy plant milk. Some milks thin the soup too much. Use one with some body like oat if you want richness.

Alternatives & Substitutions

No plant milk on hand? Use regular milk or a splash of cream if you are not dairy free. I will not judge.
Want it thicker without more potatoes? Puree a cup of the soup and mix it back in for instant body.
No vegetable stock? Use water plus an extra pinch of salt and a splash of soy sauce for umami.
Short on fresh mushrooms? Use a cup of dried mushrooms rehydrated in hot water and add the soaking liquid for extra flavor. Strain the soaking liquid first.
Hate onions raw? Use leek or shallot for a milder flavor.
Want protein? Toss in white beans or cubed tofu near the end and warm through. I like beans for texture. IMO it makes lunch more satisfying.

FAQ (Frequently Asked Questions)

Can I make this in a slow cooker? Who does not love a set it and forget it plan? Yes you can. Sauté the mushrooms and onions first then dump everything into the slow cooker and cook on low for 4 to 6 hours. Add milk near the end.
Can I use frozen mushrooms? Sure. They release a lot of water so drain them a bit and adjust sauté time. Do not expect the same texture as fresh but the flavor will be there.
Can I blend this into a smooth soup? Want it silky smooth? Go for it. Blend to your heart s desire. Leave a few spoonfuls chunky for garnish if you like contrast.
Is this vegan? Yes if you use plant based milk and vegetable stock. If you swap in dairy milk it becomes vegetarian. Still delicious.
Can I freeze leftovers? Yes. Freeze in portions for up to 3 months. Thaw in the fridge and reheat gently. Add a splash of milk when reheating if it seems thick.
Do I need to peel the potatoes? Not strictly. If they are clean and you like skins, leave them. The texture will change a bit but it still rocks.
How do I make it creamier without dairy? Use a creamier plant milk like oat or blend a cooked potato or cauliflower into the soup for natural creaminess.
