Ingredients in Keto Tomato Soup

You want the best flavor with the simplest stuff, right? Here’s my go-to lineup for creamy keto tomato soup:

  • Canned diced tomatoes (fire-roasted is really, really nice, trust me)
  • Onion (yellow or white, you pick)
  • Garlic (fresh is bold, but jarred does the trick in a pinch)
  • Olive oil or butter (let’s be real, I always pick butter)
  • Chicken or veggie broth (low-sodium if you’re picky about salt)
  • Heavy cream (don’t skimp—the richness is key)
  • Salt and pepper (just taste as you go so you don’t overdo it)
  • Dried basil or Italian seasoning (honestly, whatever’s on hand)
  • Pinch of sweetener (optional, but it balances the acidity and that’s magic for your taste buds)

That’s it. Nothing fancy or weird to track down.

How to Make Keto Tomato Soup

Okay, I promise you, making this is almost foolproof. You’ll sauté your onions in butter or oil until soft— don’t rush this part, let ’em get a little golden if you’re feeling fancy. Then the garlic goes in (don’t burn it, it’ll get bitter, trust me I’ve done it). Dump in your tomatoes, broth, seasoning, and let the whole situation simmer about ten minutes. At this point, it won’t look pretty, but hang in there.

Next, bust out your immersion blender. If you don’t have one, pour it (carefully!) into a blender. Blend it smooth— some people leave it chunky, but I’m picky. Last part, stir in the cream and simmer a few more minutes. Taste and tweak salt or pepper. Done! By the way, don’t forget to top with fresh basil if you’ve got it. Looks all five-star restaurant and stuff.

Expert Tips for the Best Results

Alright, let me hit you with a few of my favorite tricks for knockout creamy keto tomato soup.

First, good tomatoes are everything. If you splurge on one thing, let it be those fire-roasted cans. Also, when I say heavy cream, I really mean heavy cream— milk just makes it watery and sad. Got leftovers? This soup actually gets tastier after a night in the fridge. Freeze single servings for emergency comfort food moments (trust me, you’ll pat yourself on the back).

One more: always taste as you go. Sometimes canned tomatoes can be a diva with acidity; a sprinkle of sweetener calms them down. I tried skipping it once, regretted it. The last batch I made went in a little tart but a half teaspoon of allulose—absolutely saved the day.

“I didn’t think soup could be this creamy and filling without a heap of carbs. I now make it every week! Even my carb-loving husband asks for seconds.” – Robin from Ohio

  • Serve in a mug for cozy couch dinners on rainy days.
  • Crumbled bacon— don’t even get me started, it’s wild.

Common Questions

What tomatoes are best for keto tomato soup?
Honestly, canned fire-roasted tomatoes always hit the mark for flavor. Regular diced tomatoes work, too. Fresh tomatoes need longer to cook down but can taste amazing in summer.

Can I skip the cream?
Not if you want that creamy vibe! You could swap with coconut cream for dairy-free, but it changes the flavor a bit.

Is this soup okay for meal prep?
Absolutely. It stores in the fridge up to four days or freezes for about a month. I batch cook and freeze in small containers for sanity-saving lunches.

Can I make this soup chunky instead of blended?
Yep, just mash the tomatoes right in the pot and leave it rustic. The texture is different but still tasty.

What can I add for more protein?
My go-to is rotisserie chicken or even little turkey meatballs. Dump them right in and it becomes a whole meal.
