About This Recipe
Rooted in Slavic culinary traditions, this tomato and oatmeal soup exemplifies how simple pantry staples can create a satisfying meal. Unlike heavy cream-based tomato soups, this version relies on oats to provide a silky texture without excess calories. The dish is naturally gluten-free (if certified oats are used) and can be made vegan by choosing a vegetable broth. It’s an ideal choice for a quick weeknight dinner or a light lunch, offering a perfect balance of carbohydrates, fiber, and plant-based goodness. For an extra nutrient boost, consider adding a handful of red lentils or diced sweet potato when you add the broth.
Ingredients
- 15 ml (1 tbsp) olive oil
- 2 garlic cloves, minced
- ½ medium onion, diced
- 1 large carrot, diced
- ½ cup (about 80 g) rolled oats (10-minute variety)
- 120 g canned diced tomatoes
- 15 ml (1 tbsp) tomato paste
- Salt, to taste
- Freshly ground black pepper, to taste
- ¼ bunch fresh parsley, finely chopped
- Optional: 500 ml vegetable or chicken broth
Step-by-Step Instructions
Step 1: Prepare the Vegetables
Finely dice the onion and carrot, and mince the garlic. Chop the parsley for garnish and set aside. Using a sharp chef’s knife or a quality glass food processor bowl can speed up this prep work dramatically.
Step 2: Sauté the Aromatics
Heat the olive oil in a heavy-bottomed pot over medium heat. Add the onion, garlic, and carrot, then stir to coat. For even cooking and to prevent browning, cover the pot immediately. If you have an oil sprayer, you can use it to reduce the amount of oil needed.
Step 3: Steam the Vegetables
Keep the pot covered and cook for 5–6 minutes, stirring occasionally, until the vegetables are translucent and soft but not browned. This gentle steaming technique preserves the natural sweetness. For faster results, a microwave pressure cooker can be used to pre-steam the veggies in just 2 minutes.
Step 4: Add Tomato Paste
Uncover the pot and stir in the tomato paste. Cook for 3 minutes, stirring constantly, to deepen the tomato flavor. This step caramelizes the paste and adds a rich umami note. If you prefer a smoother texture, you can later use an immersion blender directly in the pot.
Step 5: Add Liquid and Oats
Pour in 500 ml of broth (vegetable or chicken), add the rolled oats, black pepper, and canned diced tomatoes. Stir well to combine. For a heartier version, include ½ cup of cooked red lentils or diced sweet potato at this stage. A food processor can help puree the tomatoes if you prefer a smooth base.
Step 6: Simmer to Perfection
Bring the soup to a boil, then reduce the heat to low and simmer for 10 minutes, stirring occasionally. The oats will swell and thicken the soup, creating a luscious texture. If you like a crispy garnish, roast some chickpeas or croutons in an air fryer while the soup simmers.
Step 7: Finish and Serve
Remove the pot from the heat. Stir in the fresh parsley, adjust salt and pepper to taste, and ladle into bowls. For a decadent touch, drizzle with a swirl of extra virgin olive oil or a dollop of dairy-free yogurt. Store leftovers in an 48-inch built-in refrigerator for up to 3 days.
Tips for the Perfect Tomato Soup
- Choose the right oats: Always use rolled oats that require 10 minutes of cooking. Instant oats will turn mushy.
- Don’t skip the toasting step: Cooking the tomato paste for 3 minutes intensifies its sweetness and reduces metallic flavors.
- Balance the acidity: If the soup tastes too tart, add a pinch of sugar or a splash of sweet wine to round out the flavor.
- Make it creamy without cream: Blend a portion of the soup with an immersion blender for a velvetier consistency. Consider a high-end espresso machine for a post-soup coffee pairing.
Flavor Variations
This soup is a blank canvas for creativity. Try these twists:
- Spice it up: Add ½ teaspoon each of turmeric, cumin, and dried oregano during the tomato paste step.
- Protein boost: Incorporate ½ cup of cooked red lentils or chickpeas along with the broth.
- Roasted sweetness: Roast diced sweet potato in a commercial countertop convection oven until tender, then stir into the soup.
- Herb garnish: Top with fresh basil, dill, or cilantro for a different aroma.
- Wine pairing: Serve alongside a glass of organic vodka for a cleansing shot, or a light red wine.
Frequently Asked Questions
Can I use quick-cooking oats instead of rolled oats?
It’s not recommended, as quick oats break down too rapidly and result in a gummy texture. Stick with rolled oats that need 10 minutes of simmering. If you only have instant oats, add them at the very end and cook for just 2 minutes.
Is this soup suitable for freezing?
Yes, it freezes well for up to 3 months. Let it cool completely, then transfer to freezer-safe containers. The texture may thicken upon thawing; stir in a little broth while reheating. Use a steam canner for longer preservation.
Can I make this soup vegan?
Absolutely. Use vegetable broth and skip any optional cheese garnish. The oats provide enough creaminess. For a richer mouthfeel, a splash of coconut milk works wonders.
How do I store leftovers?
Keep the soup in an airtight container in the refrigerator for up to 4 days. Reheat on the stovetop or in a wall oven microwave combo until piping hot.
What can I serve with this soup?
A crusty sourdough bread or a side of roasted vegetables complements the soup beautifully. For dessert, try a slice of Catalan sponge cake for a sweet finish.
This tomato and oatmeal soup is more than a meal—it’s a gentle embrace in a bowl. Whether you’re seeking comfort, nourishment, or a clever use of oats, this recipe delivers. Customize it with your favorite herbs and enjoy a taste of wholesome, homemade goodness.
