17 Cozy Keto Soup Recipes (Low-Carb & High-Comfort)

Keto soup is any soup built on a low-carb base of broth, cream, or coconut milk instead of flour, potatoes, or beans, keeping most bowls between 2 g and 8 g of net carbs per serving. This guide rounds up 17 cozy, tested recipes by category — creamy, meaty, vegetable, and global — each with a net-carb count, plus the thickeners and vegetables to leave out so soup stays keto-friendly.

Soup gets sidelined on a lot of low-carb diets because the classic versions lean on flour-thickened roux, potatoes, and noodles. It doesn't have to. Swap the starch for cream, cheese, or pureed low-carb vegetables and you get a bowl that's just as rich, with a fraction of the carbs. Below you'll find 17 recipes organized by style, a rundown of what actually makes a soup keto-friendly, and tips for turning any of these into a week of grab-and-go lunches.

Why is soup such a good fit for keto?

A bowl of keto soup delivers fat, protein, and sodium together in one dish, which is exactly what the body needs more of during the first weeks of carb restriction. Between the fat-and-protein combination that keeps you full and the salty broth that helps replace lost electrolytes, soup checks several keto boxes at once — while also being one of the easiest formats to cook in bulk.

That combination is also what makes soup practical for real life, not just theory. A big pot on a Sunday gives you several ready meals with almost no extra effort during the week, the portions are easy to control by the ladle, and a hot, savory bowl satisfies the same craving that might otherwise reach for bread or crackers. We tested each recipe style in this roundup for texture after freezing and reheating, which is why the notes below flag exactly which soups hold up in the freezer and which ones need their dairy added back in fresh — a detail most soup roundups skip.

What makes a soup keto-friendly (and what to avoid)?

A keto soup swaps flour, cornstarch, potatoes, corn, beans, rice, and noodles for keto-friendly bases like bone broth, heavy cream, coconut milk, and cream cheese. Thickness comes from pureed low-carb vegetables, egg yolks, or a pinch of xanthan gum instead of a starch slurry. Getting the base right is the single biggest factor in whether a bowl of soup fits your macros.

Keto-friendly bases and thickeners

Start with one of these instead of a flour roux:

• Bone broth or stock — the backbone of most recipes here; naturally carb-free and a good source of sodium.
• Heavy cream or full-fat coconut milk — adds richness and fat with under 1 g net carbs per tablespoon.
• Cream cheese or mascarpone — melts into broth for a velvety, low-carb thickener.
• Pureed cauliflower — mimics the texture of pureed potato soup at a fraction of the carbs.
• Egg yolks (tempered into hot broth) — classic egg-drop and avgolemono technique, adds protein and body.
• Xanthan gum — a pinch (about 1/8 teaspoon per quart) thickens broth without any meaningful carbs; whisk it in slowly to avoid clumping.

Hidden carb traps to skip

• Flour- or cornstarch-based roux
• Potatoes and sweet potatoes
• Carrots and corn (both add up fast in large amounts)
• Beans, lentils, and other legumes
• Rice, wheat pasta, or egg noodles

For a full breakdown of what to stock instead, see the keto food list. To estimate a soup you build yourself, total each ingredient on the same serving basis and document any fiber or polyol deductions. The net-carb estimate calculator can apply explicit deductions to one product label, but it does not combine a recipe or determine whether the result will produce ketosis.³

Creamy keto soup recipes

Rich, spoon-coating soups that get their body from cream, cheese, or pureed vegetables rather than flour.

Recipe	Net carbs/serving	Protein	Freezer-friendly?
Keto Broccoli Cheddar Soup	~6 g	High	No (dairy separates)
Creamy Cauliflower & Bacon Soup	~5 g	High	Partially
Keto Cream of Mushroom Soup	~4 g	Moderate	No (dairy separates)
Roasted Tomato Basil Soup with Cream	~7 g	Low-moderate	Yes, add cream after thawing

Keto Broccoli Cheddar Soup. Simmer broccoli florets in chicken broth until tender, then blend half the batch smooth and stir it back in with sharp cheddar and heavy cream. About 6 g net carbs per serving, with the sharp cheese doing the flavor work a roux normally would.

Creamy Cauliflower & Bacon Soup. Cauliflower stands in for potato here: simmer until fork-tender, blend with broth and cream, then top with crisped bacon and chives. About 5 g net carbs per serving.

Keto Cream of Mushroom Soup. Sauté cremini mushrooms in butter, deglaze with broth, and finish with cream and a touch of thyme — no flour needed for body once it's blended. About 4 g net carbs per serving.

Roasted Tomato Basil Soup with Cream. Roasting concentrates the tomatoes' natural sweetness so you need less added sugar; blend with broth, swirl in cream, and finish with fresh basil. About 7 g net carbs per serving — the highest of this group since tomatoes carry natural sugars.

Hearty keto chicken and beef soups

Protein-forward bowls built for a filling lunch or dinner.

Keto Chicken Soup. Classic chicken soup minus the egg noodles: shredded chicken, celery, a modest amount of carrot, and herbs in a rich broth. About 3 g net carbs per serving, and one of the easiest soups here to double for a big batch. For a richer, dairy-based version of this same bowl, see our keto creamy chicken soup.

Buffalo Chicken Soup. Shredded chicken, cream cheese, and hot sauce simmered into a tangy, spicy broth finished with a little blue cheese. About 5 g net carbs per serving.

Keto Taco Soup with Ground Beef. Browned ground beef, taco seasoning, diced tomatoes, and broth, topped with cheese and sour cream — skip the beans and corn a traditional taco soup uses. About 6 g net carbs per serving. If you want the same ground-beef base cooked down thicker and stew-like instead of soupy, try our keto beef chili.

Low-Carb Beef & Cabbage Soup. Cabbage replaces potatoes for bulk in this beef-and-tomato broth soup, which reheats and even improves after a day in the fridge. About 7 g net carbs per serving.

Vegetable-forward and vegetarian keto soups

Lighter, produce-heavy bowls that still fit a keto macro split when you add a fat source.

Keto Cabbage Soup. Cabbage, celery, and green beans in a tomato-herb broth; drizzle with olive oil before serving to bring up the fat percentage. About 5 g net carbs per serving.

Zucchini & Spinach Green Soup. Blend sautéed zucchini and spinach with broth and a swirl of cream for a bright, mineral-rich soup. About 4 g net carbs per serving.

Creamy Cauliflower Cheese Soup (meat-free). The same cauliflower base as above, built vegetarian with vegetable broth and extra sharp cheddar for depth. About 5 g net carbs per serving.

Egg Drop Soup. Broth thickened only by a slow, steady drizzle of beaten egg — no starch slurry at all, which is why it's the lowest-carb option on this list. About 2 g net carbs per serving.

Global and bold-flavor keto soups

Thai Coconut Chicken Soup (Tom Kha Gai). Coconut milk, lemongrass, galangal or ginger, and chicken in a broth balanced with fish sauce and lime. About 6 g net carbs per serving.

Keto French Onion Soup. Slowly caramelized onions in a beef broth, topped with melted gruyère instead of a crouton. Onions carry natural sugar, so keep the portion moderate — about 8 g net carbs per serving, the highest on this list.

Italian Sausage & Kale Zuppa Toscana. Italian sausage, kale, and a cream-finished broth stand in for the traditional potato-based version. About 6 g net carbs per serving.

Mexican Chicken Tortilla-Less Soup. All the flavor of tortilla soup — chicken, tomato, chili, lime — without the fried tortilla strips or corn. About 5 g net carbs per serving.

Keto Pho with Shirataki Noodles. A slow-simmered beef broth with warming spices, poured over shirataki noodles instead of rice noodles. About 4 g net carbs per serving.

How do you batch-cook, store, and freeze keto soup?

Broth-based soups freeze well for up to 3 months in airtight containers, while cream-based soups are best frozen without the dairy added, then finished with cream after reheating. Dairy and pureed-vegetable thickeners can separate or turn grainy when frozen and thawed, so add them fresh at serving time when possible.

• Freezes cleanly: chicken soup, taco soup, beef and cabbage soup, pho, tom kha gai (coconut milk is more freeze-stable than dairy cream).
• Freeze without the dairy, add fresh: broccoli cheddar, cream of mushroom, tomato basil, zuppa toscana.
• Portion for grab-and-go: cool completely, then freeze in single-serving containers or silicone cubes for a fast reheat.
• Reheating: thaw in the fridge overnight and reheat gently on the stovetop, whisking in a splash of cream or a little xanthan gum if the texture separated.

For a full freezing walkthrough by dish type, see our guide to freezing and storing keto meals. If you batch-cook on a set schedule, our 7-day keto meal plan shows how a pot of soup can fit into a full week's rotation.

How do you keep soup in your macro range?

Boost the fat side of a lean, broth-based soup with a spoonful of butter, a drizzle of olive oil, shredded cheese, or a dollop of sour cream stirred in just before serving. This is also how to fix a soup that reads "too lean" for your macros without adding carbs — fat calories, not starch, close the gap.

• Add protein without spiking carbs: shredded rotisserie chicken, ground beef, or a soft-boiled egg dropped in at the end.
• Watch portion creep on the higher-carb entries (French onion, tomato basil) — a smaller bowl plus a fattier topping keeps the same satisfaction with fewer carbs.
• Compare each soup's serving estimate with amounts you already use. The guide to calculating your keto macros explains the assumptions behind common daily calculations; it does not make the portion safe or appropriate for an individual.

Soup also carries a practical benefit in the first week or two of keto: as the body sheds water weight, it loses sodium and potassium along with it, and a salty, broth-based bowl is one of the easiest ways to replace both.¹ That fluid-and-electrolyte shift is a major reason people report headaches, fatigue, or lightheadedness — often called "keto flu" — during adaptation.¹ Sodium in particular helps regulate blood volume and how your muscles and nerves function, which is why bone broth is a common first line of defense.² Use the keto flu symptom checker to review timing and warning signs without assuming that your symptoms are typical adaptation.

Frequently asked questions about keto soup

Frequently Asked Questions

Is soup keto-friendly?

Yes, as long as it's built on broth, cream, or coconut milk rather than flour, potatoes, corn, or beans. Most of the recipes in this guide run 2 g to 8 g net carbs per serving, well within a standard keto daily range.

How many carbs are in keto soup?

It varies by recipe, but the soups in this roundup average around 2 g to 8 g net carbs per serving. Egg drop soup and chicken soup sit at the low end; French onion and tomato basil run higher because onions and tomatoes carry natural sugar.

Can I eat canned soup on keto?

Most canned soups are thickened with flour or cornstarch and often contain added sugar, so check the label for net carbs first. A handful of broth-based canned soups (like plain chicken broth or bone broth) are keto-friendly as a base you build on yourself.

What can I use to thicken keto soup without flour or cornstarch?

Pureed cauliflower, heavy cream, cream cheese, egg yolks tempered into hot broth, or a small pinch of xanthan gum all thicken soup without adding meaningful carbs.

Are keto soups good for weight loss?

Soup's high water and fat content can make a meal feel more filling for its calorie count, which supports weight-loss efforts. The bigger factor is still staying within your personal calorie and net-carb targets over the day.

Which vegetables should I avoid in keto soup?

Potatoes, corn, and beans are the biggest carb contributors and are best left out entirely. Carrots and onions are fine in small amounts but add up quickly if used generously.
