How to Make Slow Cooker Mediterranean Creamy Mushroom Soup
-
Prepare the crockpot: Start by lightly greasing the ceramic insert of your slow cooker with a touch of olive oil. This simple step will ensure nothing sticks and makes cleanup a breeze.
-
Clean and slice: Take the time to clean your cremini mushrooms—then slice them into ¼-inch pieces. Additionally, finely dice your onion and mince the garlic to release their flavorful aromas.
-
Sauté the vegetables: In a large skillet over medium-high heat, melt 2 tablespoons of olive oil with the butter. Add the sliced mushrooms and sauté for 7–9 minutes, until they soften and turn a lovely golden brown.
-
Add onion and garlic: Incorporate the remaining tablespoon of olive oil along with the diced onion and minced garlic into the skillet. Sauté for another 3–4 minutes, allowing the onion to soften and the garlic to become fragrant.
-
Coat with flour: Sprinkle 2 tablespoons of all-purpose flour over the mushroom mixture. Stir continuously for about 1 minute to ensure the vegetables are well-coated and the raw flour taste is cooked out.
-
Transfer to slow cooker: Carefully spoon the sautéed mushroom mixture into your prepared slow cooker.
-
Pour in broth and season: Gently pour in 4 cups of low-sodium vegetable broth. Then add the thyme, oregano, rosemary, smoked paprika, salt, and black pepper. Stir until all ingredients are well combined.
-
Set to cook: Cover and cook on LOW for 5–6 hours or on HIGH for 3–4 hours, until the mushrooms are very tender and the broth is bursting with flavor.
-
Add cream and cheese: About 20–30 minutes before serving, switch the slow cooker to LOW. Stir in the heavy whipping cream and ½ cup of grated Parmesan cheese. Gently mix until the cheese melts into the rich broth.
-
Heat until creamy: Cover and cook for another 15–20 minutes on LOW, ensuring the soup is hot and creamy without boiling, to preserve that silky texture.
-
Finish with lemon juice: Just before serving, stir in 1 tablespoon of fresh lemon juice. Taste and adjust the seasoning of salt and pepper if desired.
-
Garnish and serve: Spoon the soup into bowls and sprinkle with 2 tablespoons of chopped parsley and the remaining 2 tablespoons of Parmesan. Serve hot directly from the slow cooker for a comforting meal.
Optional: Pair with crusty bread for dipping bliss!

Slow Cooker Mediterranean Creamy Mushroom Soup Recipe FAQs
What type of mushrooms are best for this recipe?
Absolutely! For this Slow Cooker Mediterranean Creamy Mushroom Soup, I recommend using fresh cremini mushrooms. They offer a deeper, earthier flavor compared to white button mushrooms. Avoid using canned mushrooms, as they can become mushy and change the soup’s texture.

Store any leftover soup in an airtight container in the refrigerator for up to 3 days. Ensure the soup has cooled down before sealing, as this helps maintain its freshness and flavor.

Very! You can freeze the soup in freezer-safe containers for up to 3 months. Make sure to leave some space at the top of the container for expansion as the soup freezes. However, it’s best to freeze it without the heavy cream and add that during reheating for the best consistency.

No worries! If your soup turns out thicker than you’d like, simply add a bit of low-sodium vegetable broth or water while reheating until you reach your desired consistency. Stir it well to ensure even distribution of the liquid.
