Potato, Spinach and Sausage Soup
A hearty plant-based spinach sausage soup that’s perfect for colder months. If you love Olive Garden’s Zuppa Tuscana soup then you’ll love this one. With 17 g of protein per serving.

The inspiration for this recipe came after my husband made the most delicious pan-fried potatoes for dinner one night. They were so simple, but incredibly yummy. Quartered potatoes, a bit of olive oil, dried herbs and pepper flakes. I was craving them the next day, but wanted a heartier meal that would last for a few days.
If you love your soup hearty with lots of texture, then this spinach sausage soup brings its A game. Creamy potatoes, bright spinach, and tender hunks of vegan sausage.
Serve with my crusty, no-knead bread for a simple fall or winter meal that everyone will enjoy.

Ingredient and Substitution Notes
The benefit of this easy soup is that it relies mostly on pantry ingredients. You’ll also need olive oil to brown the veggies.Â
- White or yellow onion: Along with the garlic, the sauteed onion adds savory, umami flavor and helps to tie in the potatoes and sausage.
- Red potatoes: Red or yellow potatoes will work, or other small potatoes like fingerling. Depending on the size of the potatoes, you’ll need to halve or quarter them.
- Fresh baby spinach: I call for spinach, but you can sub in other dark leafy greens, like kale, if desired.
- Vegan mild Italian sausage of choice:Â My favorite brands are Field Roast, Tofurkey, and Beyond Sausage. If you are using Beyond sausage and want a crumble sausage, then I recommend removing the casing first. Impossible also makes a breakfast sausage in a tube that works great.
- Vegetable broth: I prefer a lower sodium vegetable broth, but any broth will work here. As always, I recommend that you taste your broth before adding it to the soup or at least go with a broth that you know and love. There are a few vegetable broths on the market that are so off-putting to me (namely, Trader Joe’s) and change the great flavor of the soup.Â
- Cashew cream or other non-dairy creamer: To mimic the taste of heavy cream typically used in a recipe like this, I recommend stirring in cashew cream or other non-dairy, unsweetened creamer right before serving. Oat creamer is great, or even a full-fat oat milk like Oatly. You want something with enough body and I don’t recommend using almond milk or another watery non-dairy milk.Â
- For a creamy option without any cream at all, you can also blend 1/2 cup of white beans or cannellini beans with 1/3 cup of water until very smooth. If you are looking for a soup with more heft, then I like to add in cooked white beans to this recipe sometimes.Â

How to Make
Like most soups, this one is fairly simple to put together. One of the primary reasons soups show up on my table so often this time of year.Â
Step 1: Sauté the Onion and Sausage
Heat a large soup pot over medium heat. Add the oil, onion, garlic, dried herbs and sausage. Cook, stirring often, until the sausage is well-browned and the onion is translucent and soft, about 10 minutes.

Step 2: Add the Potatoes
Add the potatoes and cook for another few minutes just to get some color on the potatoes. They will finish cooking in the broth. I like to make sure to stir often so the potatoes don’t stick.
Add the broth and simmer until the potatoes are tender, about 10-15 minutes more.

Step 3: Add the spinach
Right before serving, add the spinach, cashew cream and lemon juice. Stir in, then taste– adjusting seasoning as needed. Depending on how salty your broth is, you may need to add more salt. The acidity in the lemon juice complements this spinach sausage soup so well, giving it a bright, fresh taste.

How to make cashew cream
To make cashew cream, blend together 1/2 cup raw cashews, 1/4 cup water, a tablespoon of olive oil, a tablespoon of lemon juice, and a pinch of salt.Â
For ease with blending, I recommend soaking the cashews in water for a few hours or doing a quick soak method with hot, boiling water over raw cashews for 10-15 minutes before blending.Â

How to store leftovers
- Refrigerator: Leftovers will keep for 4 – 5 days in the refrigerator, stored in a covered container.
- Freezer: This sausage spinach soup is freezer friendly and can be stored in the freezer for up to 2 – 3 months. To freeze, let cool completely then place in freezer safe containers or freezer safe bags, leaving ½ inch head space for expansion. Thaw before reheating.Â
- Reheat:Â Reheat this soup on the stove over low heat until warm, or in the microwave with 30 second intervals, stirring after each, until warmed through.Â
Are Plant-Based Meats Healthy?
Even if you aren’t plant-based, emerging research is showing that the vegan meat alternatives like Beyond Meat are healthier than the meat counterparts; plus, plant-based meats are naturally free of cholesterol, lower in saturated fat and similar in protein content.
Since they are made from plants, they also have some fiber– especially the seitan based options. The only downside is they tend to be higher in sodium. I don’t eat them daily, but we do enjoy them a few times a week.

Potato, Spinach and Sausage Soup

Equipment
IngredientsÂ
- 1 tablespoon olive oil
- 1 cup diced white onion
- 2 large garlic cloves, minced
- 1/2 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon red pepper flakes, or more if you like things spicy, like me
- 8 ounces vegan sausage, chopped (my favorites are Tofurky and Field Roast brands, find them in the deli section near tofu. More in the blog above)
- 1 pound red potatoes or small yellow potatoes, quartered or halved depending on size
- 4 cups vegetable broth
- 6 ounces fresh baby spinach
- 1/4 cup cashew cream, or other non-dairy cream option. See how to make cashew cream.
- 1 teaspoon lemon juice
Instructions
- Heat the olive oil in a large pot over medium heat. Add the onion, garlic, oregano, basil, red pepper flakes, pinch of salt and pepper, and sausage and cook for 8-10 minutes, or until sausage is lightly browned and onion has cooked down. Stir often so the sausage doesn’t stick to the bottom of the pan.
- Add the potatoes  and cook another 2-3 minutes, stirring often.
- Add in the vegetable broth and increase heat to a low boil, then reduce to low and simmer for 10-15 minutes until potatoes are tender.
- Stir in the spinach until wilted, then remove from heat. Stir in the cashew crea and lemon juice, mixing to just combine, and taste for seasoning. Depending on the saltiness of your broth (I typically favor a low-sodium broth), you may need more salt/pepper.


Hi! My husband and I love all of your recipes. Thank you for continuing to share them.
Do you think this recipe could be changed to be made in the Instant Pot? If so, what would you suggest? Also, do you think blended tofu would work in place of the cream?
Thank you!
Hi Dimple– it’s hard to say exactly as instant pot works differently than a slow cooker and I haven’t yet tested it in here. My hunch would be 20 minutes or so, but could be less. The only thing I do worry about is the vegan sausage as cooking sausage in the instant pot can change the texture. I think blended tofu would work!
