This italian sausage and kale soup with ditalini is a one-pot weeknight meal built on browned pork sausage, torn curly kale, and small tube-shaped pasta cooked right in the broth. It lands somewhere between a rustic Italian minestra and a lighter American sausage soup, with enough body to stand as a full dinner.
The broth stays clear and savory rather than creamy, which keeps the kale from turning to mush and lets the fennel and garlic come through. You get protein, greens, and starch in a single bowl, and the leftovers thicken into something even better the next day. Making this italian sausage and kale soup with ditalini at home is surprisingly straightforward once you know the key steps.
Below you’ll find exact quantities, substitution options, and the step order that prevents the pasta from overcooking or the sausage from steaming instead of browning.

Why You’ll Love These Italian Sausage And Kale Soup With Ditalini
- One pot means fewer dishes and a broth that picks up every bit of rendered sausage fat.
- Ditalini cooks directly in the soup, so the starch naturally thickens the liquid without flour or cream.
- Curly kale holds its texture for days, making this a strong make-ahead lunch option.
- The flavor is familiar but not bland — fennel seed and a pinch of chili do the heavy lifting.
Ingredients You’ll Need
- 1 lb (450 g) mild Italian pork sausage, casings removed — gives the broth its base fat and seasoning.
- 1 tbsp olive oil — used only if the sausage renders little fat.
- 1 medium yellow onion, diced (about 1.5 cups) — builds the aromatic base.
- 4 cloves garlic, minced — added after the onion to avoid burning.
- 1 tsp fennel seed, lightly crushed — the signature flavor note in Italian sausage soup.
- 1/4 tsp crushed red pepper flakes — optional, for gentle heat.
- 6 cups low-sodium chicken broth — controls salt level since sausage is already seasoned.
- 1 (14.5 oz) can diced tomatoes, with juice — adds acidity and body.
- 1 cup ditalini pasta, dry — small enough to spoon easily with broth.
- 1 large bunch curly kale (about 8 cups torn) — stems removed, leaves torn into bite pieces.
- 1/2 tsp salt, adjusted to taste — added late because sausage and broth both carry sodium.
- 1/4 tsp black pepper — fresh ground preferred.
- 1/2 cup grated Parmesan, for serving — stirred in at the table, not boiled.
Ingredient Substitutions
Mild Italian pork sausage: Replace with an equal weight of hot Italian sausage if you want more spice, or with ground turkey seasoned with 1 tsp fennel and 1/2 tsp salt for a lighter version. Turkey renders less fat, so keep the olive oil in the pan or the onion will stick. Expect a milder, slightly drier broth and a shorter brown time since poultry cooks faster than pork. Storing leftover italian sausage and kale soup with ditalini correctly keeps it tasting good for days.
Curly kale: Swap for an equal volume of lacinato (dinosaur) kale, which has thinner leaves and a slightly sweeter taste. Lacinato wilts about 2 minutes faster, so add it just after the pasta starts to soften. Avoid tender baby spinach here — it breaks down in under a minute and turns the broth murky. For the best results with this italian sausage and kale soup with ditalini, read through all the steps before starting.
Ditalini pasta: Use an equal weight of small elbow macaroni or orzo if ditalini is unavailable. Orzo is rice-shaped and releases more starch, so cut the broth by 1/2 cup at the start and add splash-wise later. Both hold up in fridge storage better than long pasta, which snaps when reheated.
Low-sodium chicken broth: Use homemade stock or a standard canned broth, but reduce added salt to a pinch and taste before the final seasoning. Full-salt broth combined with sausage can push the soup past pleasant into salty, especially after reduction. If using bone broth, expect a darker color and a slightly gelatinous chill when refrigerated. For another easy option, check out our italian broccoli.
Step-by-Step Instructions
- Set a 6-quart Dutch oven on medium heat and add the sausage. Break it into pea-sized pieces with a wooden spoon and cook 8–10 minutes until browned and crisp at the edges; the fat should be rendered and the pan lightly sizzling, not smoking.
- Using a slotted spoon, move the sausage to a plate, leaving the rendered fat in the pot. If less than 1 tablespoon of fat remains, add the olive oil now.
- Add the diced onion to the fat and cook on medium-low heat for 5 minutes, stirring often, until translucent and softened at the corners but not browned.
- Stir in the garlic, crushed fennel seed, and red pepper flakes. Cook 1 minute until fragrant and the garlic looks glossy, not golden.
- Pour in the chicken broth and diced tomatoes with juice, scraping the browned bits from the pot bottom with your spoon. Those bits carry the deepest flavor and should fully loosen.
- Return the browned sausage to the pot, raise heat to medium-high, and bring the soup to a steady boil that pops small bubbles across the surface.
- Add the dry ditalini and stir once. Lower to medium heat and simmer 10 minutes, until the pasta is tender with a slight bite at the center.
- Add the torn kale in two handfuls, pressing it down so it submerges. Simmer 5 minutes more, until the leaves are wilted, dark green, and tender but not slippery.
- Turn off the heat. Stir in the black pepper and taste; add the salt only if the broth needs lift. The sausage and peppers method shows a similar browning baseline if you want a side.
- Ladle into bowls and top with grated Parmesan at the table. Serve immediately while the pasta is firm.
Pro Tips
Brown the sausage in a single layer and resist stirring for the first 3 minutes so a crust forms; that crust is where the broth gets its color. A sheet pan roasting habit does not apply here — stove-top browning beats oven for a soup base.
Crush the fennel seed with the flat side of a knife instead of using it whole, or you’ll hit sharp bitter pops in the broth. The seed opens up its sweet anise note once cracked and warmed in fat.
Cook the ditalini just to al dente in the soup if you plan to refrigerate it; the pasta keeps absorbing liquid as it cools. For rustic bread on the side, undercooked pasta by a minute works best.
Add the Parmesan off heat and at the bowl, not in the pot, or the soup turns cloudy and the cheese clumps. A salsa verde drizzle on top cuts the richness if you find it heavy.
Common Mistakes to Avoid
Adding kale at the same time as the pasta is the most common error; the greens overcook and the pasta stays hard because they need different times. Keep a 5-minute gap as written.
Boiling the soup hard after the pasta goes in breaks the ditalini and dumps starch too fast, turning the broth gluey. A gentle medium heat simmer keeps the texture right.
Skipping the deglaze step leaves browned sausage residue stuck to the pot, which then burns and turns the broth bitter. Scrape the bottom when the broth goes in.
Serving Suggestions
Ladle the soup into wide shallow bowls so the kale and pasta sit visible under the broth. A chunk of lard bread on the side soaks up the last spoonfuls.
For a fuller table, pour a small Italian margarita alongside; the orange and Campari balance the fennel. Keep the soup as the main and the drink as the accent.
Storage and Reheating
Cool the soup to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. The pasta will swell, so the soup reads thicker on day two — that is expected.
Reheat on medium-low heat on the stove, stirring every few minutes, until the center reaches 165°F (74°C) for food safety since it contains pork. Microwave reheating works but stir halfway or the bowl heats unevenly.
This soup freezes for up to 2 months, though the kale softens further and the ditalini gets faintly mushy. Freeze before adding Parmesan and stir the cheese in after thawing.
Recipe Variations
White Bean Version
Replace the ditalini with 1 (15 oz) can cannellini beans, drained, added in the last 5 minutes instead of pasta. The soup turns thicker and more stew-like, with a creamy bean bite replacing the starch of the pasta. Skip the boiling step for pasta and just simmer to warm the beans through.
Spicy Calabrian Version
Swap the red pepper flakes for 1 tablespoon Calabrian chili paste added with the garlic. The broth takes on a fruity heat and a faint red tint that pairs well with the fennel. Use hot sausage too if you want a two-level burn that still reads savory.
Potato and Kale Version
Cut 2 small Yukon gold potatoes into 1/2-inch cubes and add them with the broth; simmer 12 minutes before the pasta. The potatoes break down slightly and add a buttery body, making the soup gluten-free if you omit the ditalini. This version needs less salt because the potato absorbs seasoning.

Ingredients
Instructions
-
Brown the sausage
Set a 6-quart Dutch oven on medium heat and add the sausage. Break it into pea-sized pieces with a wooden spoon and cook 8–10 minutes until browned and crisp at the edges, with the fat rendered and the pan lightly sizzling but not smoking.
-
Remove sausage, add fat
Using a slotted spoon, move the sausage to a plate, leaving the rendered fat in the pot. If less than 1 tablespoon of fat remains, add the olive oil now so the onion will not stick.
-
Cook the onion
Add the diced onion to the fat and cook on medium-low heat for 5 minutes, stirring often, until translucent and softened at the corners but not browned. This builds the aromatic base without scorching the sugars.
-
Add aromatics
Stir in the garlic, crushed fennel seed, and red pepper flakes. Cook 1 minute until fragrant and the garlic looks glossy, not golden, to avoid burning the aromatics.
-
Deglaze with broth
Pour in the chicken broth and diced tomatoes with juice, scraping the browned bits from the pot bottom with your spoon. Those bits carry the deepest flavor and should fully loosen so the broth stays clear rather than bitter.
-
Boil and add pasta
Return the browned sausage to the pot, raise heat to medium-high, and bring the soup to a steady boil that pops small bubbles across the surface. Add the dry ditalini and stir once, then lower to medium heat and simmer 10 minutes until the pasta is tender with a slight bite at the center.
-
Add kale and finish
Add the torn kale in two handfuls, pressing it down so it submerges, and simmer 5 minutes more until the leaves are wilted, dark green, and tender but not slippery. Turn off the heat, stir in the black pepper, and taste; add the salt only if the broth needs lift.
-
Serve with Parmesan
Ladle into bowls and top with grated Parmesan at the table, not boiled in the pot. Serve immediately while the pasta is firm so the soup stays brothy rather than gluey.
