Step 3

Stir in the garlic and cook until fragrant, about 2 minutes then add the asparagus, red potatoes, carrots, and thyme leaves.

Step 4

Season with the rest of the salt and the black pepper and continue to cook for 7-10 minutes until the potatoes and asparagus become tender.

Stir in the chicken broth and almond milk and bring to a boil, and cook until thickened, about 2-3 minutes, stirring often. Taste, and add more salt and pepper if needed. Turn off the heat and allow to cool slightly.

Step 7

Preheat the oven to 400 degrees F.
