Recipe Notes

As I said, you can multitask while making this super yummy keto tomato soup recipe because of the bake and simmer time. Here’s what you need to know:

Ingredient Notes

Tomatoes – I love heirloom tomatoes in this keto tomato soup recipe but romas work well too. When you quarter them up, try to get them all the same size so they roast evenly.

Bacon – You’ll cook the bacon in a large stockpot and reserve some of the grease. This is where you’ll start building your fond for those layers of yummy flavor that develop in this keto tomato soup recipe.

Aromatic Veggies – You’ll need to sauté the onions and garlic in your stockpot — this helps reduce bitterness and coax out the sweet mellow flavors. Plus, it adds to the fond you’re building for the base of your soup.

Fresh Herbs – It may seem like a lot but fresh herbs have a delicate profile, so it takes more of them. Simmering the basil and thyme in the soup helps coax out the deeper more complex flavors.

Tools To Make

Making this keto tomato soup recipe is about as simple as it can get, and you don’t need any special gadgets! Here’s what you need to know!

• Baking Sheet – for roasting tomatoes
• Large Stockpot – to build soup in
• Blender (Immersion or Tabletop) – I prefer to just toss the ingredients in my Blendtec and let it work its magic!

You’ve probably got all this stuff in your kitchen already.

Storing Tips

Your soup will keep best in a food-grade airtight container in the fridge.

Can You Freeze This?

Oh yeah!! This keto tomato soup recipe freezes really well. I like to freeze it in single-serve portions. Whether you freeze it in Ziploc bags or food-grade containers, it’s important to leave some room for the liquid to expand.

Meal Prepping Tips

I love making this keto tomato soup recipe while I’m doing meal prep.

I like to whip up a double batch and freeze most of it in single-serve portions that I can pull out one at a time for low carb dinners or keto side dishes. The rest stays in the fridge for the most nutritious, decadent low carb meals.

Keto Tomato Soup Recipe Variations

This low carb tomato soup recipe is sooo flexible. You can easily tweak this delicious bowl of sunshine to suit your dietary goals. Here are a few healthy recipes suggestions…

How Can I Add More Greens?

Technically, you could add some greens to this low carb tomato soup recipe, but it’ll change the flavor of your dish.

Instead of adding greens to your tomato soup, you could try making lettuce soup, broccoli cauliflower soup or cabbage roll soup. You can also serve it with a crisp green salad on the side.

Can I Make This Spicy?

Of course, you can! This creamy roasted low carb tomato soup calls for some red pepper flakes but only enough to add flavor.

If you’ve got soup on the brain and you love spicy like I do, you may want to try making keto chili . Curried butternut squash soup is also pretty good and it’s got a little kick to it.

How Can I Make This Soup Creamy?

This low carb tomato soup is decadently creamy as it is, which is part of its yummy factor. I wouldn’t adjust the cream too much for fear of changing the beautiful flavor.

If you really love creamy soup, you should try keto butternut squash soup. It’s just so much easier to make something like a super creamy summer squash soup or pumpkin soup rather than running the risk of messing up your low carb tomato soup recipe.

What Other Veggies Can I Sneak In?

I love sneaking low carb veggies into soup recipes. Soup is the perfect disguise for those harder to handle veggies that may be missing from your diet.

This low carb tomato soup does have a decent amount of veggies in it but if you’re looking for a myriad of nutrition, you should make low carb vegetable soup instead! If you’re on a veggie kick or you just want something a little different, you may enjoy spaghetti squash soup. Its every bit as creamy and delicious as low carb tomato soup, only with different veggies. Brussel sprout soup will also give you a metropolis of wholesome greens that are sure to satisfy.
