From the roundup: 24 High Protein Dinner Recipes Easy Enough for Busy Weeknights
This chicken sausage and cannellini bean stew is one of those slow cooker dinners I actually trust on a school night. The active work is about 15 minutes: brown the sausage, soften the onion and garlic in the same pan, then scrape everything into the slow cooker and leave. That skillet step matters more than it sounds. Skipping it once taught me that the broth tastes noticeably thinner without those browned edges on the sausage.
After six hours on low, the cannellini beans are creamy and the broth pulls together into something thick enough to scoop with bread. The spinach goes in at the very end, lid back on for ten minutes, and it wilts down to almost nothing so even the kids who pick around greens barely notice it. If you have a Parmesan rind in the freezer, tuck it in before you walk out the door. It adds a quiet richness to the broth that is hard to get any other way.
This makes six solid servings, which in my house means dinner plus lunch the next day. The stew thickens overnight in the fridge, so I always keep a little extra broth on hand for reheating.
Why you will love this
- 15 minutes of morning prep, then the slow cooker handles the next six hours completely hands-off
- Chicken sausage and two cans of cannellini beans make this genuinely filling without feeling heavy
- One skillet plus the slow cooker insert, cleanup is minimal on a busy weeknight
- The broth thickens naturally as it cooks, no cornstarch or cream needed
- Leftovers reheat well and taste even better on day two once the flavors settle
Tips for success
- Do not skip browning the sausage. Two to three minutes per side in a hot skillet builds color on the cut edges, and that color is what gives the broth its depth. The slow cooker cannot do this on its own.
- Scrape the skillet after the sausage comes out. Cook the onion in those drippings and stir the tomato paste directly into the pan for 30 seconds before it goes into the slow cooker. That 30 seconds makes the paste taste less raw.
- Add the spinach only in the last 10 minutes. If it goes in at the start it turns gray and breaks down completely, which is fine for flavor but looks unappetizing by dinner.
- Taste for salt after the spinach wilts, not before. The Parmesan rind and the sausage both add saltiness as they cook, so seasoning too early usually means overshooting.
If the stew turns out too thin
- Mash about half a cup of the cannellini beans against the side of the slow cooker insert and stir them back in. The starch thickens the broth in a few minutes without changing the flavor.
- Leave the lid slightly ajar for the last 30 minutes on high if you want more evaporation.
- Thin broth is usually a sign the tomatoes had more liquid than expected. Next time, drain about half the juice from the diced tomato can before adding it.
Substitutions
Turkey sausage or a mild Italian pork sausage both work in place of chicken sausage. Just make sure it is fully cooked before slicing, since the slow cooker is not hot enough to safely cook raw sausage through. Great northern beans or navy beans are a fair swap for cannellini if that is what you have. Fire-roasted diced tomatoes add a slightly smokier background flavor if you want to change things up.
For the spinach, chopped kale works but add it about an hour before the stew finishes rather than at the end, since it needs more time to soften. If someone at the table will not touch greens at all, just leave the spinach out entirely. The stew is complete without it.
Make-ahead and storage
You can brown the sausage and cook the onion mixture the night before, then refrigerate everything separately so loading the slow cooker in the morning takes under five minutes. Leftovers keep well in an airtight container in the fridge for up to four days. The stew thickens considerably as it sits, so add a splash of broth when reheating on the stovetop over medium-low heat.
This stew freezes well for up to three months. The beans hold their texture better than most, though they do soften a little more after thawing. Freeze in individual portions for easy lunches, and thaw overnight in the refrigerator before reheating.

Slow Cooker Chicken Sausage and Cannellini Bean Stew
Ingredients
Equipment
Method
- Heat the olive oil in a large skillet over medium-high heat. Add the sliced sausage in a single layer and cook for 2 to 3 minutes per side until the cut edges are nicely browned. You are not cooking them through, just building color and flavor on the surface. Remove from heat.
- Add the diced onion to the same skillet and cook for 2 minutes, scraping up any browned bits from the bottom. Stir in the minced garlic and tomato paste and cook for 30 seconds until fragrant. This step adds a lot of flavor to the base of the stew.
- Transfer the browned sausage, onion and garlic mixture, drained cannellini beans, diced tomatoes with their juices, and chicken broth into the slow cooker. Stir in the Italian seasoning, red pepper flakes, salt, and black pepper. Nestle in the Parmesan rind if using.
- Cover and cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours. The stew is ready when the broth is rich and slightly thickened and the beans are very tender.
- About 10 minutes before serving, stir in the baby spinach. Put the lid back on and let it wilt for 5 to 10 minutes. Fish out and discard the Parmesan rind if you used one.
- Taste and adjust salt as needed. Ladle into bowls and serve with crusty bread for soaking up the broth. A light sprinkle of grated Parmesan on top is a nice finishing touch.
