Protein Cream of Potato Soup

A bowl of protein cream of potato soup brings together the familiar comfort of creamy potatoes, savory vegetables, and melted cheddar with an added protein boost from cottage cheese and milk. The result is a rich, cheesy soup with a smooth finish and plenty of hearty potato flavor.

Yellow potatoes create the creamy base as they simmer in vegetable broth with onion, celery, carrot, and garlic. The vegetables are sautéed first, building the soup’s savory foundation before the potatoes become tender enough to blend.

Cottage cheese is blended directly into the soup rather than served as a topping. Along with the milk and cheddar, it contributes to the soup’s 16 grams of protein per serving while helping create its creamy consistency.

This high-protein cream of potato soup takes 40 minutes from start to finish, including 10 minutes of preparation and 30 minutes of cooking. It can be served hot with chives and/or bacon crumbles, and leftovers can be refrigerated or frozen for another meal.

Ingredients

• 1 tbsp avocado oil

• 1 yellow onion (diced)

• 2 celery stalks (diced)

• 1 medium carrot (diced)

• 3 garlic cloves (minced)

• 1 ½ lbs yellow potatoes (peeled and diced in 1 inch cubes)

• 4 cups vegetable broth

• 1 tsp salt

• ½ tsp black pepper

• ½ cup 2% milk ((I used Fairlife))

• ½ cup heavy cream

• 1 cup cottage cheese

• ½ cup shredded cheddar cheese

How to Make Protein Cream of Potato Soup

1. Heat the avocado oil over medium heat in a large pot or Dutch oven. Add the diced onion, celery, and carrot. Sauté for 3–4 minutes, until the onion is translucent. Add the minced garlic and sauté for 1 minute more.

2. Add the diced potatoes, vegetable broth, salt, and black pepper. Stir, then bring the mixture to a simmer. Cover the pot and simmer for 15 minutes, or until the potatoes are fork-tender. Keep the lid on during this stage so the soup retains moisture and cooks evenly.

3. Remove the pot from the heat. Stir in the milk and heavy cream, then add the cottage cheese. Blend the soup with an immersion blender until smooth. If using a high-speed blender instead, carefully transfer the hot soup in batches. Vent the blender lid and cover it with a clean dish towel to help prevent hot splatters.

4. Return the blended soup to the pot. Heat it over low heat, stirring in the shredded cheddar until the cheese has fully melted and the soup is smooth. Do not boil the milk, cream, or cottage cheese; gentle low heat helps prevent curdling. Taste just before serving and add more salt or pepper as needed.

The potatoes should be just fork-tender rather than overcooked. The complete active cooking time is 40 minutes, with 10 minutes of preparation and 30 minutes of cooking. If browned bits form on the bottom of the pot during the vegetable sauté, scrape them up with a wooden spoon or heat-safe spatula after adding the broth.

About Protein Cream of Potato Soup

Classic cream of potato soup commonly starts with potatoes, milk, and water, sometimes with cheese included. This protein cream of potato soup follows that familiar creamy potato foundation while adding cottage cheese, milk, and shredded cheddar to increase its protein content.

The vegetable base also gives the soup a more developed savory starting point. Onion, celery, carrot, and garlic are sautéed before the broth and potatoes go into the pot. After the potatoes simmer until tender, the dairy and cottage cheese are blended into the soup, and cheddar is melted in at the end. That sequence keeps the dish recognizable as cream of potato soup while giving it a distinctly cheesy, protein-focused profile. For another recipe idea, explore High Protein Broccoli Cheddar Soup.

Variations

• Potato cream cheese soup: Swap the heavy cream with cubed cream cheese for a different creamy variation.

• Spicy potato soup: Add up to 1 teaspoon of red pepper flakes during the vegetable sauté.

• Bacon-flavored soup: Cook the onion, celery, and carrots in bacon fat instead of avocado oil for additional flavor.

The substitutions offer other ways to adjust the soup while keeping its general structure. Use whole milk or half-and-half in place of heavy cream. Monterey Jack, Colby Jack, sharp white cheddar, or a mixture of cheeses can replace the shredded cheddar. Plain Greek yogurt made with 2% or whole milk can replace cottage cheese.

For the broth, homemade vegetable stock or chicken broth or stock can be used instead of vegetable broth. These alternatives change the ingredient combination without requiring a different cooking sequence. For another recipe idea, explore High Protein Broccoli Cheddar Soup.

Serving Suggestions

Serve the soup hot with chives and/or bacon crumbles. The toppings add a simple finishing touch to the smooth, cheesy potato soup.

For a fuller meal, pair it with crusty bread or dinner rolls, such as toasted French baguette, ciabatta, or sourdough. Cheddar biscuits bring another cheesy element, while sweet, buttery cornbread offers a contrasting complement. Protein cornbread can add another protein boost.

A selection of loaded potato soup toppings also works well for a customizable meal. Offer shredded cheese, sour cream, black olives, green onions, and other supported toppings so each bowl can be finished individually.

Storage and Make-Ahead

Prepare the vegetables ahead by dicing the onion, celery, and carrots. Refrigerate the prepared vegetables until you are ready to cook the soup. For another make-ahead idea, see Creamy Tuscan White Bean Soup (High Protein).

For leftovers, cool the soup to room temperature before freezing. Refrigerated soup keeps covered in an airtight container for up to 5 days. Once cooled, place it in a freezer-safe container and freeze for up to 3 months.

To thaw frozen soup, defrost it overnight in the refrigerator, or thaw it on the stovetop over low heat, stirring frequently, for 10–15 minutes or until warmed through. For refrigerated soup, reheat it on the stovetop over low heat for 3–5 minutes or in the microwave on gentle heat for 1–2 minutes, until hot.

Keep reheating gentle rather than bringing the soup to a boil. The recipe’s dairy ingredients are warmed over low heat during cooking, and the same low-heat approach is used for reheating.

Troubleshooting

• The potatoes are mushy or the soup is grainy: The potatoes may have cooked too long. Simmer them for 15 minutes, or only until they are just fork-tender, before blending.

• The soup lacks depth of flavor: Browned bits may be stuck to the pot. After adding the vegetable broth, scrape the bottom with a wooden spoon or heat-safe spatula to loosen them into the soup.

• The dairy curdles: The milk, cream, or cottage cheese may have been boiled. Remove the pot from the heat before adding the milk and cream, then warm the blended soup over low heat while the cheddar melts.

• Hot soup splatters during blending: A high-speed blender needs careful handling. Blend in batches, vent the lid, and cover it with a clean dish towel. An immersion blender avoids transferring the hot soup between containers.

• The soup needs more seasoning: Taste just before serving and add more salt or pepper as needed. Salt and pepper are key to bringing out the soup’s flavor.

Why You’ll Love It

Protein cream of potato soup keeps the familiar appeal of a creamy, cheesy potato soup while adding cottage cheese, milk, and cheddar as protein-contributing ingredients. Each serving provides 16 grams of protein, making the soup a substantial choice for a hearty lunch or an easy, lighter dinner.

The soup also brings several useful textures together in one pot. Sautéed vegetables create the savory base, simmered yellow potatoes become smooth when blended, and melted cheddar adds a cheesy finish. The process uses a large pot or Dutch oven and an immersion blender, with a high-speed blender available as an alternative.

It can be served simply with chives or bacon crumbles, or paired with bread, biscuits, or cornbread. Leftovers can be stored in the refrigerator for up to 5 days or frozen for up to 3 months, giving the recipe value beyond its first serving.

Pro Tips for Success

Cut the onion, celery, and carrot into similar-sized pieces. Matching pieces sauté at a similar rate, so the vegetable base develops evenly during the initial 3–4 minutes over medium heat. Add the garlic afterward and give it only 1 minute of sautéing before adding the potatoes and broth. For another recipe idea, explore 3-Ingredient Tomato Lentil Soup {vegan, high-protein, oil-free}.

Use the covered simmer to manage both moisture and texture. Once the broth, potatoes, salt, and pepper are combined, keep the lid on while the potatoes simmer for 15 minutes. Check for fork-tenderness rather than cooking beyond that point. Overcooked potatoes can become mushy or grainy.

A few handling details make the blended soup smoother and safer to prepare:

• Scrape browned bits from the bottom of the pot after adding the broth.

• Remove the soup from the heat before stirring in the milk and cream.

• Blend the cottage cheese into the soup until smooth.

• If using a high-speed blender, work in batches, vent the lid, and cover it with a clean dish towel.

• Return the soup to the pot and use low heat while the cheddar melts.

• Taste and adjust the salt and pepper just before serving.

These steps protect the soup’s texture while preserving the flavor developed during the vegetable sauté.

Flavor and Texture

This is a creamy, cheesy soup with potatoes and vegetables. Yellow potatoes are simmered until fork-tender and blended with cottage cheese, milk, and cream, creating a smooth base.
