Creamy Roasted Potato Leek Soup With Spinach

The aroma still takes me back: to a crisp autumn evening, watching the leaves fall outside my grandmother’s kitchen window. She was humming a tune as she pulled a steaming Dutch oven from the oven. The earthy scent of roasted potatoes and sweet leeks filled the air, a promise of warmth and comfort. With a flourish, she swirled in some cream and declared it “magic in a bowl.” This potato leek soup with spinach is my attempt to recapture that magic – and I’m so excited to share it with you!

Recipe Overview

Prep Time: 20 minutes
Cook Time: 50 minutes
Total Time: 1 hour 10 minutes
Servings: 6-8
Yield: About 8 cups
Dietary Type: Vegetarian (adaptable to vegan)

Ingredients

2 1/2 lbs Yukon Gold potatoes, peeled and cut into 3/4-inch cubes
4 Leeks, white and light green parts, washed and chopped
3 tablespoons Olive oil
3 cups Spinach, lightly packed
2/3 cup White wine (replace with chicken broth if desired)
6 cups Chicken broth
1/2 cup Half-and-half (substitute with full-fat coconut milk for a vegan option)
1/2 cup Parmesan cheese, shredded, plus extra for garnish (omit for vegan)
1/4 cup Bacon, crumbled, or 1/4 cup bacon bits (to garnish – optional and can be omitted for vegetarian or vegan option)

Equipment Needed

Large Dutch oven
Cutting board
Sharp knife
Immersion blender (or regular blender/food processor)
Measuring cups and spoons

Instructions

Preheat your oven to 400°F (200°C). This high heat will ensure the vegetables roast properly, developing a rich, caramelized flavor that’s essential to the soup.
In a large Dutch oven, combine the potatoes, leeks, and olive oil. Stir well to evenly coat the vegetables with the oil. This ensures even roasting and prevents sticking.
Roast the vegetables for 40-45 minutes, stirring occasionally, or until the potatoes are tender. Stirring prevents burning and ensures even cooking. You’ll know they’re ready when a fork easily pierces through a potato cube.
Add the spinach to the Dutch oven and stir to combine with the roasted vegetables.
Return the Dutch oven to the oven and roast for 5 more minutes, or until the spinach is wilted. The residual heat and moisture will quickly wilt the spinach, adding a vibrant color and subtle earthy flavor to the soup.
Remove the Dutch oven from the oven and place it on the stovetop over medium heat.
Pour in the white wine (or chicken broth, if substituting) and 1 cup of chicken broth. Stir well, scraping up any browned bits from the bottom of the pan. These browned bits, known as fond, are packed with flavor and will add depth to the soup.
Add the remaining 5 cups of chicken broth.
Using an immersion blender, puree the soup until smooth and creamy. If you don’t have an immersion blender, carefully transfer the soup in batches to a regular blender or food processor, being cautious of hot liquids. Return the pureed soup to the Dutch oven.
Stir in the half-and-half (or coconut milk, if using) and Parmesan cheese (if using). Stir until the cheese is melted and the soup is heated through. Taste and adjust seasoning as needed. Remember, salt enhances the flavors, but be mindful of the salt content of the broth.
Serve hot, topped with shredded Parmesan cheese (if using) and crumbled bacon or bacon bits (if using).

Expert Tips & Tricks

Roasting is key: Don’t skip the roasting step! It brings out the natural sweetness of the potatoes and leeks.
Don’t overcrowd the pan: If your Dutch oven is too small, roast the vegetables in batches to ensure even browning.
Deglaze thoroughly: Make sure to scrape up all the browned bits from the bottom of the pan after roasting. That’s where the flavor is!
Adjust the consistency: If the soup is too thick, add more chicken broth until you reach your desired consistency. If it’s too thin, simmer uncovered for a few minutes to allow some of the liquid to evaporate.
Spice it up: For a touch of heat, add a pinch of red pepper flakes or a dash of hot sauce to the soup.
For a richer flavor: Try using roasted garlic instead of fresh. Add it to the Dutch oven during the last 15 minutes of roasting.
Make Ahead: You can roast the vegetables up to 2 days in advance. Store them in an airtight container in the refrigerator. When ready to make the soup, proceed with step 7.

Serving & Storage Suggestions

Serve the potato leek soup hot, garnished with a sprinkle of fresh herbs like chives or parsley, a swirl of cream, or a dollop of sour cream (if not vegan). A crusty loaf of bread is the perfect accompaniment for dipping.

Storage:

Room Temperature: Do not leave at room temperature for more than 2 hours.
Refrigerator: Store the soup in an airtight container in the refrigerator for up to 3-4 days.
Freezer: Freeze the soup in freezer-safe containers for up to 2-3 months. Thaw overnight in the refrigerator before reheating. Note that the texture may change slightly after freezing, especially if you used dairy.

Reheating:

Reheat gently in a saucepan over medium heat, stirring occasionally, until heated through. You may need to add a splash of broth or water if the soup has thickened during storage.
