This creamy, flavor-packed white bean soup has been my go-to on busy weeknights and quiet Sundays alike. I first discovered this combination on a cold evening when my pantry was modest and my desire for comfort food was large. Two cans of beans, a handful of simple vegetables and herbs, and a splash of white wine transformed into an aromatic, velvety soup that filled the house and warmed our bellies. The texture is unusually luxurious for such humble ingredients: tender beans and soft potatoes melt into a thick, almost chowder-like broth while a hint of rosemary and a drizzle of olive oil keep the profile bright and Mediterranean.

What makes this soup special is its speed and versatility. It goes from stove to bowl in about 25 minutes, is entirely plant-based, and relies mostly on pantry staples: canned beans, tomato paste, and frozen spinach. That said, the soup doesn’t taste like a shortcut — it smells like a slow-simmered pot because of the caramelized onion and the wine reduction step. I serve it to guests when I want something comforting and unfussy; friends often ask for the recipe, and family members request extra bread for dunking. This is a one-pot answer to satisfying, wholesome cooking that’s both frugal and surprisingly elegant.

Ingredients

• Cannellini beans: 2 cans (14 oz each), drained and rinsed. Canned white beans provide creaminess and body; choose a low-sodium brand if possible and rinse well to reduce excess salt.
• Onion: 1 medium, diced. A yellow or sweet onion gives a natural sweetness when softened and is the aromatic base for developing flavor.
• Celery: 1 stalk, diced. Offers subtle brightness and texture balance; rinse and trim the base before chopping.
• Carrot: 1 large, diced. Adds mild sweetness and color; peel if the skin is thick and slice uniformly for even cooking.
• Garlic: 1 to 2 cloves, minced or pressed. Fresh garlic adds a fragrant layer — adjust to taste but avoid burning it during sautéing.
• Frozen spinach: 1 cup (about 7 oz frozen). An easy green to toss in; if using fresh, plan to add it later in the cooking time so it wilts but stays bright.
• Potatoes: 2 medium, peeled and cut into 1- to 1.5-inch chunks. They help thicken the broth and create a silky body when the beans and potatoes break down.
• Olive oil: 1 tablespoon for sautéing, plus extra for drizzling at the end. Use a good extra-virgin oil for finishing for best flavor.
• Tomato paste: 1 tablespoon. Adds umami and a touch of acidity to round flavors — cook it briefly to deepen its sweetness.
• White wine: 1/3 cup. A splash lifts the flavors and helps deglaze the pan — substitute with additional broth if you avoid alcohol.
• Rosemary: 1 fresh sprig (or 1 tablespoon chopped or 1/2 teaspoon dried). Its piney aroma is central to the Mediterranean feel; remove the sprig before serving if you used whole stems.
• Vegetable broth: 2 cups. Low-sodium broth is best so you can control final seasoning; hot water plus a cube works in a pinch.
• Seasonings: 1/2 teaspoon paprika (optional), 1/2 teaspoon fine salt plus additional to taste, and 1/8 teaspoon freshly ground black pepper to start.

Instructions

Warm the base: Heat 1 tablespoon olive oil in a large, heavy-bottomed pot over medium heat until shimmering but not smoking. Add the diced onion, carrot, and celery and cook, stirring often, until the onion softens and becomes translucent, about 4 to 6 minutes. Look for glossy edges on the onion and softened carrot pieces as visual cues. Add aromatics and solids: Add the garlic, drained beans, tomato paste, potato chunks, rosemary (sprig or chopped), and paprika if using. Stir constantly for about 1 minute to toast the tomato paste and bloom the spices without burning the garlic. Toasting the paste deepens its flavor and reduces any raw tomato tang. Deglaze with wine: Pour in the 1/3 cup white wine and stir, scraping any browned bits from the bottom of the pot. Allow the wine to simmer and reduce for about 1 minute so its alcohol cooks off and its acidity concentrates, which brightens the overall dish. Add greens and liquid: Stir in the frozen spinach and pour 2 cups hot vegetable broth (or hot water). Add a good pinch of salt and the black pepper. Increase heat to bring the pot to a gentle boil, then cover, reduce heat to low, and simmer for 15 minutes. The potatoes should be fork-tender and the beans should start to break down into a creamy body. Finish and adjust seasoning: Remove from heat when potatoes are soft and soup has thickened. If you used a rosemary sprig, fish it out now. Taste and adjust salt and pepper: start conservatively if your broth was salted. For a silkier texture, mash a cup of the soup against the side of the pot with your spoon, or pulse briefly with an immersion blender. Serve: Ladle into bowls, drizzle with extra-virgin olive oil, and finish with extra freshly ground black pepper. Serve with crusty whole-grain bread for dunking, or grate parmesan on top if you are not keeping it vegan.

Storage Tips

Cool the soup to near room temperature before covering and refrigerating. Store in airtight containers for up to 3 days. For freezing, portion into freezer-safe containers leaving about 1 inch of headspace; freeze up to 2 months. To reheat, thaw overnight in the refrigerator if frozen, then simmer gently on the stove until piping hot. Add a splash of water or broth if it has thickened significantly. Reheat in single bowls in the microwave for quick lunches, stirring halfway through for even heating.

Ingredient Substitutions

If you don’t have cannellini beans, great northern or navy beans work equally well — drain and rinse them the same way. Replace white wine with an equal amount of broth and 1 teaspoon lemon juice if avoiding alcohol. Swap frozen spinach for 10 oz fresh spinach, adding it in the last 3 to 5 minutes so it wilts but remains vibrant. Use sweet potato or Yukon gold in place of regular potatoes for a different texture and a slightly sweeter finish. If you love heat, add a pinch of red pepper flakes when you add the garlic.

Serving Suggestions

Serve with thick slices of crusty whole-grain or sourdough bread for dipping. A finishing drizzle of high-quality extra-virgin olive oil elevates the flavor and mouthfeel. For non-vegans, a grating of parmesan or Pecorino Romano adds savory depth. Garnish with a few rosemary leaves, chopped parsley, or a squeeze of lemon for brightness. Pair with a simple green salad and a light white wine or sparkling water to keep the meal balanced and fresh.

Cultural Background

This style of white bean soup sits firmly in Mediterranean home cooking where beans, olive oil, and herbs are pantry fundamentals. Many coastal regions across Italy, Greece, and Spain have variations — some use pancetta or pork for a meatier version, while others emphasize garlic and lemon. The technique of simmering beans with potatoes to create a creamy base is a humble, traditional method that transforms inexpensive staples into hearty comfort food.

Seasonal Adaptations

In winter, add chopped root vegetables like parsnip or a splash of cider vinegar to brighten the flavors. In spring and summer, use fresh young spinach or toss in chopped spring greens at the end. For holiday dinners, garnish with toasted pine nuts and serve with herb-roasted vegetables. The soup scales well: for larger gatherings, double the recipe and simmer in a wide, shallow pot for faster heat exchange.

Meal Prep Tips

Make a double batch and portion into individual containers for easy weekday lunches. The soup reheats beautifully and develops deeper flavor after a day in the fridge. Pack with a small container of grated cheese and a slice of toasted bread for a complete meal on the go. If freezing, defrost in the fridge overnight and reheat gently on the stove to preserve texture.

Whether you are feeding a family, preparing lunches for the week, or looking for a quick weeknight solution, this white bean soup becomes more than the sum of its parts — simple ingredients, care in technique, and a habit of finishing with good olive oil make it memorable. I hope it becomes one of your favorites, too.
