Ingredients

Scale

1/2x 1x 2x 3x

• 1 lb Italian sausage (mild or spicy)
• 4 slices bacon, chopped
• 1 small onion, diced (about ½ cup)
• 2 cups radishes, quartered
• 3 cups chicken broth

• ½ tsp crushed red pepper flakes (optional)
• ½ tsp black pepper
• ½ tsp salt (adjust to taste)
• ¼ cup grated Parmesan for topping

Instructions

1. Cook the Bacon: Heat your Dutch oven over medium heat. Add chopped bacon and cook 5–7 minutes until crispy. Remove bacon and set aside, leaving the rendered fat in the pot.
2. Brown the Sausage: Add Italian sausage to the pot and cook 5–6 minutes, breaking it apart with a spoon, until lightly browned.
3. Add Onions & Garlic: Stir in diced onion and garlic. Cook 2–3 minutes until fragrant and softened.
4. Add Radishes: Add quartered radishes and stir to coat them in the sausage mixture.

1. Add Broth & Simmer

   Pour in chicken broth and water.
   Bring to a boil, then reduce heat to medium-low.
   Simmer for 12–15 minutes, until radishes are tender like potatoes.

1. Add Cream

   Reduce heat to low. Slowly pour in heavy cream while stirring.
   Do not boil — keep it at a gentle simmer for 3–4 minutes.

    

1. Add Spinach

   Stir in spinach and let it wilt for 1–2 minutes.
