1-Step 1: Prepare the Potatoes Begin by preparing the Yukon gold potatoes. Pierce them with a fork and microwave until cooked through. This should take about 5-7 minutes depending on your microwave. Once cooked, dice the potatoes into bite-sized pieces and set aside. If you don’t have a microwave handy, no worries. Just chop the potatoes into even pieces, boil them until tender, and you’re good to go; it’s all about making this cozy soup easy and enjoyable for your whole family.

2-Step 2: Sauté the Aromatics Heat 1 tablespoon of oil in a large pot over medium heat. Add the finely chopped onion and sauté until it becomes caramelized and translucent, which should take about 5-7 minutes. This step is crucial for building the flavor base of your soup. Once the onions are nicely browned, add the sliced carrots to the pot and cook until they begin to tenderize, about 5 minutes more.

3-Step 3: Create the Roux Transfer the sautéed vegetables and the cooked potatoes to a bowl and set them aside. Reduce the heat to medium-low, then add the butter and the remaining 2 tablespoons of oil to the pot. Let the butter melt completely, then stir in the flour. Cook this mixture for about one minute, stirring constantly to prevent burning. This roux will serve as the thickening agent for your soup, giving it that rich, creamy consistency.

4-Step 4: Build the Soup Base Gradually add the vegetable broth to the roux while stirring constantly to prevent lumps from forming. Next, pour in the milk, dried thyme, kosher salt, and freshly ground black pepper. Continue stirring as the sauce thickens, which should take about 3-5 minutes. The mixture should become smooth and velvety as it cooks. Once the base has thickened appropriately, stir in the dry white wine and cook for an additional minute to allow the alcohol to evaporate and the flavors to meld.

5-Step 5: Combine and Simmer Add the cooked vegetables (onions, carrots, and potatoes) and the thawed frozen peas to the thickened sauce. Stir everything together gently to combine, then cook the soup over medium-low heat for 15 minutes, stirring occasionally to prevent sticking. This simmering time allows all the flavors to come together beautifully and ensures the vegetables are perfectly tender. Taste the soup and adjust the seasoning with additional salt and pepper if needed. Serve hot for the best experience!
