Loaded with garden veggies, spicy sausage, and big flavor — all in a slow cooker so you don’t have to stand over a stove.
A few summers ago, I was staring at a counter full of zucchini from the garden and a fridge full of “what am I gonna do with this?” I had a pack of Italian sausage I forgot to freeze, a can of beans, and half an onion looking sad in the crisper drawer. Try our This Cozy Tortellini Soup Is Like Wrapping Up in a Wool Blanket — But Way Tastier next.
So I tossed everything in the slow cooker — not expecting much, if I’m honest — and let it go.
Y’all… it was a hit. My husband said it was the best soup I’d ever made (and he doesn’t hand those out freely). Even the teenager who “doesn’t do vegetables” ate two bowls. I scribbled it down in my recipe notebook that night with a big star and a little note: “MAKE AGAIN!!” If you like this, you'll love our Smoked Sausage and Potato Skillet.
Why You’ll Love It Like I Do
-
No stovetop drama — everything cooks low and slow
-
It’s packed with summer veggies but still hearty and satisfying
-
Freezes beautifully (if you manage to have leftovers)
-
Feels like comfort food, but doesn’t weigh you down
-
Smells like an Italian deli in the best possible way
Here’s What You’ll Need
(and yes, most of it’s probably already in your kitchen)
-
2 lbs Italian sausage – spicy or mild, whatever your crew likes
-
2 carrots, peeled and chopped
-
2 celery stalks, chopped
-
1 white onion, diced (or use what you’ve got — red, yellow, whatever)
-
1 bell pepper, diced (I like red for sweetness, but green works too)
-
2–3 small zucchinis, chopped small (don’t peel ‘em, just wash and dice)
-
1 (15.5 oz) can diced tomatoes – juice and all
-
1 (15 oz) can cannellini beans, drained and rinsed
-
4 cups chicken or veggie broth – homemade if you’re fancy, boxed if you’re tired
-
1 tbsp garlic powder – or a few fresh cloves if you’re feelin’ motivated
-
1 tbsp Italian seasoning – store-bought or your own blend
-
1 tsp red pepper flakes – optional, but adds a little heat
-
Salt & pepper, to taste
-
¾ cup shredded Parmesan, for serving (the real stuff, if you can swing it)
How to Make It (No Fuss, Promise)
Step 1: Brown the sausage
Heat up a big ol’ skillet and cook the sausage, breaking it up with your spoon as it browns. Don’t worry about cooking it all the way — just get it mostly done. Drain off the grease and set it aside.

Tip: If you’re really pressed for time, you can even skip browning. But you’ll miss out on that deep flavor, so I try not to.
Step 2: Dump it all in the crockpot
Toss in the sausage, all your veggies, the tomatoes, beans, broth, garlic, seasoning, salt, and pepper. Give it a stir, slap the lid on, and walk away. That’s it. For another easy option, see our Oven Baked 5-Ingredient Hoover Stew.
Step 3: Let it do its thing
Set your slow cooker:
-
High for 4–5 hours
-
Low for 6–8 hours
That’s it. No stirring, no babysitting. Just let it bubble away while you do your life.
Step 4: Serve with cheese (lots of it)
When the soup is hot, the veggies are tender, and everything smells like heaven, ladle it into bowls and sprinkle with a handful of Parmesan. Maybe even a drizzle of olive oil and a few extra red pepper flakes if you’re feeling bold.
And if you’ve got crusty bread or a hunk of garlic toast nearby? Even better.
Little Ways to Change It Up
-
Want it meatless? Skip the sausage and add more beans or chopped mushrooms
-
Feeding a crowd? Add cooked pasta at the end (like ditalini or elbow macaroni)
-
Out of zucchini? Sub in yellow squash, spinach, or whatever you’ve got on hand
-
Want it thicker? Stir in a spoonful of tomato paste or mash some of the beans
Leftovers That Taste Even Better Tomorrow
-
Fridge: Keeps for 4–5 days. Flavors get deeper overnight.
-
Freezer: Freeze in individual portions and reheat on the stove or microwave — maybe add a splash of broth if it thickens too much.
-
Lunch win: Pour it in a thermos and thank yourself later.
