Mashed potatoes are a classic comfort food, but traditional recipes often rely on butter and cream for richness. What if you want a plant-based, oil-free version that still delivers fluffy texture and rich flavor? This recipe uses roasted garlic to add depth without fat, and offers tips to keep your mashed potatoes light and airy without over mixing. Plus, you’ll learn about the health benefits of the ingredients used.

Ingredients and Their Health Benefits
This recipe uses simple, whole-food ingredients that provide nutrition beyond just taste.
Potatoes: Choose starchy varieties like Russet or Yukon Gold for fluffiness. Potatoes are a good source of vitamin C, potassium, and fiber, especially when you keep some skin on. They provide complex carbohydrates for energy without fat.
Roasted Garlic: Roasting garlic mellows its sharpness and brings out a sweet, nutty flavor. Garlic contains compounds like allicin, which research suggests may support heart health and immune function.
Plant-Based Milk: Unsweetened almond, oat, or soy milk adds creaminess without dairy or oil. These milks are low in calories and can be fortified with calcium and vitamin D.
Salt: Enhances flavor. Use sea salt or Himalayan salt for trace minerals.
How to Roast Garlic for Maximum Flavor
Roasting garlic transforms its pungent raw taste into a mellow, buttery flavor that enhances mashed potatoes without oil.
Preheat your oven to 400°F (200°C).
Slice the top off a whole garlic bulb to expose the cloves.
Place the bulb on a piece of foil, drizzle with a splash of olive oil or water, and wrap tightly.
Roast for 25-30 minutes until cloves are soft and golden.
Let cool, then squeeze the roasted garlic out of the skins.
Roasted garlic adds richness and depth, making oil unnecessary in this recipe.
Step-by-Step Recipe for Fluffy Oil-Free Mashed Potatoes
Ingredients
2 pounds Russet or Yukon Gold potatoes, peeled and cut into chunks
1 whole bulb roasted garlic (see above)
1/2 cup unsweetened plant-based milk
1/4 cup vegetable broth
1 teaspoon salt (adjust to taste)
Fresh herbs (optional, such as chives or parsley)
Instructions
Place potatoes in a large pot and cover with cold water. Add a pinch of salt.
Bring to a boil, then reduce heat and simmer until potatoes are fork-tender (about 15-20 minutes).
Drain potatoes well and return them to the hot pot. Let them sit for a minute to evaporate excess moisture.
Use a potato masher or ricer to mash the potatoes gently. Avoid electric mixers or over mixing to prevent gluey texture.
Add the roasted garlic cloves, salt, vegetable broth and about half of the plant-based milk.
Fold the ingredients together gently, adding more milk as needed to reach your desired creaminess.
Taste and adjust salt or add fresh herbs if desired.

Tips for the Fluffiest Mashed Potatoes
Use starchy potatoes: Russet or Yukon Gold create fluffier mash than waxy types.
Start with cold water: This ensures even cooking and prevents a gummy texture.
Drain and dry potatoes: Letting them sit in the hot pot after draining removes excess water.
Mash by hand: Use a potato masher or ricer instead of a blender or mixer to avoid overworking the starch.
Add liquids gradually: This helps control the texture and prevents runniness.
Nutritional Benefits of This Recipe
This oil-free mashed potato recipe offers several health advantages:
Low in fat: Without butter or oil, the dish is naturally low in fat and calories.
Rich in potassium: Potatoes provide potassium, which supports heart and muscle function.
Immune support from garlic: Roasted garlic contains antioxidants and compounds that may boost immunity.
Dairy-free and vegan: Suitable for those with lactose intolerance or following a plant-based diet.
Fiber content: Keeping some potato skin adds fiber, which supports digestion.

Variations and Serving Suggestions
Add steamed cauliflower to the potatoes for extra creaminess and nutrients.
Stir in nutritional yeast for a cheesy flavor without dairy.
Top with fresh herbs like rosemary or thyme for added aroma.
Serve alongside roasted vegetables or a hearty lentil stew for a balanced meal.

These actually taste just as good as ones with tons of butter. 🧈 I’m shocked and happy at the same time.
I was hoping for mashed potatoes without oil or plant-based butter. I've always used your other mashed potato recipe, but I'm going to give this one a try for Thanksgiving. Thanks for an even healthier version.
