Soups & Stews
This low fiber creamy tomato soup recipe delivers comforting warmth without the digestive discomfort, perfect for sensitive stomachs or post-surgery recovery. 💛 I developed it after years of testing soups that were either too rough or not flavorful enough—this version balances smooth texture with rich tomato taste using ingredients that are gentle on digestion.
The secret lies in blending ripe tomatoes with refined flour for thickening instead of high-fiber vegetables, while canned tomatoes provide natural sweetness without the tough skins. A touch of cream adds velvety richness, and well-cooked onions provide subtle flavor without fiber content.
The result is a soup that's both nourishing and easy to digest, with no rough textures to worry about.
What makes this recipe special is its ability to soothe while satisfying—every spoonful delivers creamy comfort without the heaviness of traditional tomato soups. The blend of canned tomatoes, broth, and cream creates a naturally smooth texture that's gentle on sensitive systems, while herbs and spices add depth without overpowering.

Ingredients for low fiber soup
Gentle ingredients that blend into velvety perfection—no rough textures here.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Crushed Tomatoes 🍅 | 2 cups | San Marzano preferred, no skins |
| All-Purpose Flour 🌾 | ¼ cup | For silky thickening, sifted |
| Heavy Cream 🥛 | ½ cup | Full-fat for velvety texture |
| Yellow Onion 🧅 | 1 whole | Finely diced, slow-cooked |
| Garlic Cloves 🧄 | 2 cloves | Minced, aromatic depth |
| Vegetable Broth 💧 | 3 cups | Low-sodium preferred |
| Olive Oil 🫒 | ¼ cup | Extra-virgin for richness |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Dried Basil 🌿 | ½ tsp | Or 1 tbsp fresh chopped |
| Dried Oregano 🍃 | ¼ tsp | Italian variety preferred |
| Sugar 🍬 | 1 tsp | Balances acidity gently |
| Butter 🧈 | 1 tbsp | Unsalted, for finishing |
The tomatoes are the heart of this soup, so San Marzano makes all the difference—they're naturally sweet and smooth. Grab a can of the crushed variety (no chunks or skins) from Whole Foods or Trader Joe's—their brands are consistently reliable. The onion needs to cook low and slow to melt into sweetness without adding fiber, so don't rush this step. For the broth, low-sodium is key—high sodium can irritate sensitive systems. I always double-check labels since even 'natural' broths can be sneaky with salt content.
No San Marzano? Any good-quality canned tomatoes work—just make sure they're crushed, not diced. The flour is non-negotiable for that silky texture, but if you're avoiding gluten, arrowroot powder at half the amount works beautifully. Fresh basil is ideal, but dried works at one-fifth the quantity—just remember it's more concentrated. Want extra richness? Add 2 tbsp cream cheese at the end for a velvety upgrade. The sugar balances the acidity without overpowering—adjust to taste if your tomatoes are particularly tart.
This soup tastes even better the next day as flavors meld. Store in an airtight container for up to 5 days in the fridge, or freeze for 3 months—it reheats like a dream. For meal prep, I make a big batch and portion it into single-serving containers so each bowl is ready to grab. The cream separates slightly when chilled, so just give it a quick stir before serving. Perfect for sensitive stomachs, post-surgery recovery, or anyone craving comfort without texture worries.

Step-by-step instructions for low fiber creamy tomato soup
Here's how to create a velvety, comforting tomato soup that's gentle on digestion while packed with rich flavor.
🍳 Step 1: Sauté Aromatics Until Fragrant
Heat the 0.25 cup olive oil in a large pot over medium heat. Add the finely diced yellow onion and cook for 5-6 minutes until completely soft and translucent. This slow cooking ensures the onions dissolve into the soup without adding texture.
Add the 2 cloves minced garlic cloves and cook for another 30 seconds until you can smell that sweet, aromatic essence. Here's the thing—garlic burns fast, so keep an eye on it. You want it fragrant, not bitter. Stir constantly during this last minute to prevent browning.
👨🍳 Step 2: Create a Silky Roux
Lower the heat to medium-low and sprinkle in the 0.25 cup all-purpose flour all at once. Whisk vigorously for 1-2 minutes until the mixture turns a pale golden color and smells nutty. This is your roux foundation—it'll give the soup that luxurious creaminess without any lumps.
I like to use a whisk for this step because it creates more surface area for the flour to cook evenly. If it starts to darken too quickly, reduce the heat slightly. You're aiming for a light roux that's just beginning to thicken but not yet browned.
🥘 Step 3: Build the Creamy Base
Pour in the 2 cups canned crushed tomatoes and 3 cups vegetable broth all at once. Stir well to combine, then add the 0.5 tsp salt, 0.25 tsp black pepper, 0.5 tsp dried basil, 0.25 tsp dried oregano, and 1 tsp sugar. Bring the mixture to a gentle simmer over medium heat.
Let it cook uncovered for 15-20 minutes until the soup thickens slightly and the flavors meld together. You'll know it's ready when the edges of the pot show a slight thickening and the aroma is rich and inviting. Here's where the magic happens—the acidity from the tomatoes balances perfectly with the sweetness of the sugar and the depth of the spices.
🔥 Step 4: Finish with Cream and Butter
Reduce the heat to low and stir in the 0.5 cup heavy cream. Let it warm through for 2-3 minutes, stirring occasionally. The cream should heat gently but not boil—this prevents curdling and maintains that silky texture we're after.
Remove the pot from heat and stir in the 1 tbsp butter until melted and fully incorporated. This final touch adds another layer of richness that makes the soup truly exceptional. Taste and adjust seasoning if needed—you might want to add a pinch more salt or sugar to balance the flavors perfectly.
⏰ Step 5: Blend for Ultimate Smoothness
For a completely smooth texture, use an immersion blender to purée the soup directly in the pot. Work in batches if needed, blending until completely silky. If you prefer some texture, you can skip this step—but remember, we're going for that gentle, low-fiber experience.
Return the soup to low heat if needed to maintain serving temperature. Ladle into bowls and garnish with a drizzle of olive oil and a sprinkle of fresh basil if you like. This soup is at its best served warm, with crusty bread to soak up every last drop of that velvety goodness.
Pro Tips For Making Low Fiber Soup
- Cook Onions Slow: I learned this the hard way—if you rush the onions, they’ll turn bitter and gummy. Sauté them in a little olive oil over medium-low heat for 8-10 minutes until they’re soft, translucent, and just starting to caramelize. That’s when they’ll actually sweeten the soup instead of overpowering it.
- Blend Flour First: Skip the lumps by whisking 1-2 tablespoons of all-purpose flour into a small bowl with a splash of cold water before adding it to the pot. Stirring dry flour into hot liquid almost always creates clumps, and this soup needs a smooth, velvety texture to stay low-fiber.
- Simmer Cream Gently: Heavy cream scalds faster than you’d think. Once you stir it in, keep the heat at the lowest setting possible—just enough to maintain a gentle bubble. Walk away if you have to; burned cream ruins the whole dish, and you’ll taste every bit of it.
- Salt the Tomatoes Early: Add a pinch of salt to the crushed tomatoes as soon as they hit the pot. It helps break down their texture slightly and mellows their acidity before the cream goes in. I know it sounds counterintuitive, but it makes the final soup taste richer without extra seasoning.
Perfect pairings for this low fiber soup
Bread Pairings
For the ultimate low-fiber experience, serve this soup with soft white bread or plain baguette slices—both dissolve beautifully without adding rough textures. I love using Schar's white bread (gluten-free if needed) or French bread from my local Italian deli.
The crust should be slightly crisp to contrast the creamy soup while still being gentle on digestion. 🥖
Creamy Add-Ins
Boost richness with grated Parmesan cheese (about 2 tbsp) or a dollop of sour cream on top. For extra protein, stir in ¼ cup shredded cooked chicken breast—it blends seamlessly into the silky texture.
My rescue dog Biscuit loves when I sneak a tiny piece of chicken into mine, but I always check for any lingering bones first!
Herb Garnishes
Fresh basil leaves or chopped chives add vibrant color and a bright herbal note without altering the soup's gentle texture. For a pop of acidity, drizzle with balsamic glaze (just 1 tsp)—it cuts through the creaminess beautifully.
I keep a small jar of Penzeys Italian Seasoning on hand for quick garnishes when fresh herbs aren't available.
Light Sides
Pair with steamed white rice or mashed potatoes (made with butter and milk) for a complete low-fiber meal. The rice soaks up the soup beautifully, while the potatoes add a comforting element. For a lighter option, serve with cucumber slices—they provide crunch without fiber content, balancing the soup's creaminess.
Beverage Pairings
A sparkling water with lemon cleanses the palate between spoonfuls, while white wine spritzers (mix 3 parts Prosecco with 1 part soda water) add a refreshing contrast.
For non-alcoholic options, chilled chamomile tea complements the soup's warmth and soothes digestion. My grandmother always said tea after soup was the secret to a happy belly! 🍵
Nutrition facts
Frequently asked questions
Can I make this soup without dairy?
Replace the heavy cream with ½ cup coconut milk (full-fat for best texture) and use olive oil instead of butter. The soup will still be creamy, though slightly lighter. For extra richness, add 2 tbsp nutritional yeast when blending—it adds a cheesy flavor without dairy.
How do I adjust this for a gluten-free diet?
Swap the all-purpose flour for arrowroot powder or cornstarch (use half the amount). The soup will thicken just as well while staying gluten-free. Test with 1 tbsp first to ensure proper consistency, as arrowroot thickens more quickly than flour.
Why does my soup get watery when reheating?
This happens when the starches break down during reheating. To fix it, stir in 1 tbsp cornstarch mixed with 2 tbsp cold water while reheating on low heat. Stir constantly until thickened. For prevention, store leftovers in a sealed container and reheat only until warm—overheating causes separation.
Can I use fresh tomatoes instead of canned?
Fresh tomatoes work, but you'll need to peel and seed them first to remove skins and seeds (high-fiber parts). Simmer 1 lb peeled tomatoes until very soft (15 minutes), then blend until smooth. This takes more effort but gives a fresher taste. For easiest results, stick with canned crushed tomatoes.
Is this soup safe for someone with IBS?
Yes, but monitor tolerance as individual reactions vary. The recipe avoids common triggers like raw vegetables, legumes, and high-fiber ingredients. For extra caution, serve at room temperature or chilled—heat can sometimes irritate sensitive stomachs. Always consult a dietitian for personalized advice.
