Instructions
Prep the Potatoes: Wash and peel the potatoes, then cut each into 4-6 pieces. Place the potatoes in a large pot filled with cold, salted water.
5 medium Yukon gold potatoes
Cook the Potatoes: Place onto the stovetop and bring to a boil, then reduce to a slow boil and cook until fork-tender, about 20 minutes
Prep The lentils: While the potatoes cook, add dry red lentils to another pot with 2 cups of water and a pinch of salt.
Cook the Lentils: Bring to a boil, then reduce heat to a simmer. Cook for 15-20 minutes, or until the lentils are soft and mushy, with little to no water remaining (drain if necessary).Instant Pot Option: For a shortcut, cook the lentils in an Instant Pot on the bean setting for 15 minutes.
1 cup dry red lentils
Reserve & Drain: Once the potatoes are tender, reserve 1 cup of the potato water, then drain well and return them to the pot.
Mash the Potatoes and Lentils: Add the cooked red lentils, salt, oregano, and vegan butter. Using a potato masher or fork, mash everything together, gradually adding reserved potato water until you reach a smooth, creamy consistency.
2 tablespoon oregano, 1 tablespoon vegan butter, 1 tablespoon garlic powder, ¼ teaspoon salt, reserve some of the potato cooking water
Serve: Serve the high-protein mashed potatoes immediately or store them for later (see storage instructions).
Notes
Storage Tips: Store leftover mashed potatoes in an airtight container in the refrigerator for up to 4 days. When reheating, add a splash of reserved potato water or dairy-free milk to bring back the creamy texture.Recipe Tip: When you cook your red lentils make sure to cook them a tad longer to get them to break down. Test with a spoon to make sure it mashes easily before adding them to the potatoes.
