What Makes This Recipe Special?
This isn’t just any soup; it’s a symphony of flavors. You have the delicate, rich earthiness of shiitake and baby bella mushrooms mingling with the sweetness of caramelized onions. And don’t even get me started on how the kale adds that lovely color and a bit of vibrant crunch! Plus, a splash of coconut milk? Oh boy, that adds an unexpected creaminess that just brings the whole dish together. It’s like a culinary hug, inviting you to take a deep breath and smile as you bring a spoonful to your lips.
But here’s a little secret—I totally go off script sometimes. Feel free to experiment with different mushrooms or even toss in some fresh herbs if you’re feeling adventurous! The beauty of cooking is that even the “oops” moments can end up being the best part sometimes.
Ingredients
- 2 tbsp extra-virgin olive oil
- 1 large sweet onion, sliced 1/2 inch thick
- 4 cloves garlic, finely chopped
- 1 tsp sea salt or pink salt
- 1/2 tsp freshly cracked black pepper
- 2 cups whole shiitake mushrooms
- 2 cups baby bella or cremini mushrooms, sliced
- 4 cups organic chicken broth or vegetable broth
- 2 cups loosely chopped kale leaves
- 1/2 cup coconut milk or coconut cream
Each of these ingredients plays a crucial role in creating that comforting bowl of goodness. The olive oil brings richness while keeping it light—just enough to sauté those onions to golden perfection without being overly greasy. When caramelizing, take your time; the sweetness that comes from slowly cooking the onions is where the magic happens!
Speaking of onions, if you’re anything like me and tend to panic when chopping onions (hello, tears!), try using a sharp knife or chilling them in the fridge for a bit before cutting. It might not sound like much, but trust me, your mascara will thank you!
And the mushrooms? They aren’t just any mushrooms; I prefer a combination of shiitake for their unique flavor and baby bellas for their earthiness. You might want to wander over to your local farmers’ market to get the freshest ones—your soup deserves it!
Oh, and please don’t skimp on the kale! It adds a pop of color and a healthy boost—who doesn’t want that in their healthy meal plans for two? If kale is not your jam, feel free to swap it with fresh spinach, but keep in mind that you’ll want to add it towards the end since it cooks faster.
How to Make It Step-by-Step
Let’s dive into the nitty-gritty of bringing this delicious bowl of soup to life. Grab your ingredients and some good tunes; it’s time to cook!
-
Heat the Oil: In a large pot over medium heat, drizzle in the olive oil. As it warms, take a moment to admire the little dance of bubbles forming; it’s almost therapeutic, isn’t it?
-
Caramelize the Onions: Toss in your sliced sweet onions and a sprinkle of salt. Let them slowly caramelize for about 10-15 minutes, stirring occasionally. The golden brown goodness that will form is what you dream about, the sweet aroma wafting through your home. Honestly, this is where the soup begins to feel like a celebration.
-
Add Garlic and Mushrooms: Once the onions are beautifully caramelized, stir in the garlic and cook for another minute. Ooh, can you smell that? Now, add the shiitake and baby bella mushrooms, which will start to release their moisture and shrink down. Stir everything together and let the mushrooms cook for about 5-7 minutes until they’re tender and golden.
-
Pour in the Broth: Now, let’s make this soup feel personified with all its cozy warmth. Pour in the organic chicken or vegetable broth, and consider it your soul’s hug. Bring everything to a gentle simmer and allow it to cook for about 10 minutes. Listen to it! That soft bubbling sound is practically music.
-
In with the Kale: Toss in the chopped kale leaves and stir to incorporate. You might think, “Wow, that looks like a lot of greens,” but trust me, they’ll wilt down nicely. Let it simmer for another 5 minutes until the kale is tender but still vibrant green.
-
Finish with Coconut Milk: Here comes my favorite part! Reduce the heat to low, stir in the coconut milk or cream, and watch as it swirls into the soup, creating a luscious texture. Give it a taste; adjust the seasoning by adding more salt or pepper if desired.
-
Serve and Enjoy: Ladle the soup into bowls, maybe sprinkle a bit of fresh black pepper or a dash of olive oil on top, and dig in! Yes, this soup requires a big spoon, and yes, you’ll want to hug your bowl.
Like I mentioned earlier, don’t hold back on personalizing this recipe; when you make it, truly make it your own. Throw in some herbs, a splash of lemon juice, or even some crushed red pepper for a hint of warmth. Cooking, I’ve learned, is about joy and improvisation!
Tips for Best Results
-
Sautéing: Don’t rush the caramelization process. It may take a little longer, but it transforms the onions into little nuggets of flavor, which enriches the soup.
-
Mushroom Variety: Experiment with different mushrooms. A mix of more earthy or seasonal varieties can change the flavor profile entirely.
-
Creaminess Level: If you prefer a creamier texture, blend a portion of the soup with an immersion blender and stir it back in. Be careful, though! It’s easy to get carried away and turn it into a puree!
Ingredient Substitutions & Variations
Feel free to swap in your favorite greens if kale isn’t available. Spinach, Swiss chard, or even collard greens can work beautifully!
If you’re looking to transform this into a vegan option, simply substitute the chicken broth with vegetable broth and ensure your coconut milk is dairy-free.
For a heartier meal, you could also throw in some cooked quinoa or brown rice—hello, extra nutrients! Another idea? Use this soup as a sauce over pasta for a twist on a weeknight dinner.
Directions
- ❤️ In a large pot, heat olive oil and caramelize sliced onions.
- Add minced garlic, shiitake, and baby bella mushrooms; cook until tender.
- Stir in broth; bring to a simmer for 10 minutes.
- Toss in kale, simmer for 5; mix in coconut milk and adjust seasonings.
Pairing this heavenly soup with a crisp baguette or some cheesy toasts is a match made in heaven. A good movie, perhaps a pot of tea or wine (if you prefer!), and that’s what I call a perfect night.
Pairing Ideas (Drinks, Sides, etc.)
-
Drink: A warm mug of chamomile tea or a refreshing lemony sparkling water complements this soup beautifully.
-
Sides: Think crusty bread or a light salad—something that brings some texture and complements the soup’s smoothness.
-
Dessert: End on a sweet note with a slice of apple pie or some fresh berries with a sprinkle of sugar.
How to Store and Reheat Leftovers
Guess what? This soup keeps like a champ! If you have any leftovers (which, let’s be real, is rare in my house), let it cool completely before transferring it to an airtight container. It should last in the fridge for up to a week.
When reheating, do it slowly on the stove just until warmed through. If you microwave it, make sure to do so in short intervals, stirring in between to avoid hot spots. Nobody wants a burnt tongue while trying to enjoy their perfect soup.
Make-Ahead and Freezer Tips
If you plan to make this soup ahead of time, go right ahead! Just prepare the soup as directed and freeze it in an airtight container, leaving some space for expansion. It can last up to three months in the freezer. To be honest, I’ve even found it keeps well, because it only gets better as the flavors meld together!
Common Mistakes to Avoid
-
Overcooking the Onions: They should be caramelized, not burnt! Keep an eye on your heat; medium-low is typically your best bet.
-
Too Much Broth: Start with less broth if you want a thicker soup. You can always thin it out later!
-
Skipping the Coconut Milk: I know it seems optional, but trust me, skipping it is a mistake you’ll regret. It adds a creamy, dreamy texture that elevates the whole dish.
