Instructions
Pierce the potatoes several times with a fork and microwave until tender, about 5–10 minutes depending on size. Cool slightly, then dice into ½- to 1-inch cubes. Set aside.
Heat a large pot or Dutch oven over medium-high heat. Add 1 tablespoon olive oil and sauté onions until deeply golden and caramelized, about 15–20 minutes.
Add carrots and cook until tender, about 5–7 minutes. Transfer vegetables to the bowl with the potatoes.
Reduce heat to medium. Add butter and remaining olive oil to the pot. Once melted, whisk in flour and cook for 1 minute.
Slowly whisk in vegetable broth, milk, thyme, salt, and pepper until smooth and thickened.
Stir in apple juice or extra vegetable broth and cook for 1 additional minute.
Add the cooked vegetables and peas. Simmer on medium-low for 15 minutes, stirring occasionally.
