Easy Cooking Guide
- Getting Ready
- Warm up a 5-6 quart Dutch oven to medium heat (350°F/177°C). Have everything measured and ready to go before you start cooking.
- Cooking The Meat
- Put oil in and wait till it shimmers (350°F/177°C). Drop in sausage and break it into small ½-inch chunks. Let it cook 6-8 minutes until it hits 165°F (74°C) inside and gets a nice brown outside (Pantone 7518 C).
- Adding Flavor Builders
- Throw onion and garlic in with the sausage. Cook about 3-4 minutes until onions turn see-through and smell good. Add mushrooms and cook 4 more minutes until they release water then soak it back up.
- Making The Base
- Pour in broth and tomatoes. Let it bubble gently (200°F/93°C) for 10 minutes. Sprinkle in herbs, salt and pepper.
- Making It Creamy
- Turn heat down to low (180°F/82°C). Slowly mix in cream and Parmesan until everything blends together. The sauce should stick to the back of a spoon when done.
- Finishing Touches
- Add handfuls of spinach bit by bit, stirring until just soft but still bright green. Soup should be 165-170°F (74-77°C) when you serve it.
Ways To Make It Your Own
You can jazz up this soup by tossing in some pasta like tortellini or tiny shells to make it go further. Try swapping spinach for baby kale or arugula if you want different flavors. If you're watching calories, ground turkey or shredded rotisserie chicken works great too. Don't be afraid to throw in whatever veggies are in season—sweet corn, zucchini, or colorful bell peppers all work wonderfully.

How To Save Leftovers
Keep any extra soup in a sealed container in your fridge for up to 3 days. When you want to eat it again, warm it slowly over low heat (165°F/74°C), giving it a stir now and then so it stays nice and creamy. Don't let it boil or the cream might separate and ruin the texture.
Recipe FAQs
- → Can I use turkey sausage?
Absolutely, turkey sausage is a great lighter choice. It won’t be as rich, but it still tastes delicious.
- → Can I substitute the heavy cream?
You can use half-and-half, but the texture will be thinner. To get that thick, creamy feel, heavy cream works best.
- → How long does it stay fresh?
Keep it in a sealed container in the fridge for up to 3 days. Reheat it slowly to avoid separating the cream.
- → Is freezing an option?
It’s not the best choice since frozen cream-based soups tend to separate when thawed. It’s better fresh or stored in the fridge.
- → What pairs well with it?
Some warm crusty or garlic bread is amazing alongside. A fresh green salad is a great light side too.
