These healthy mashed potatoes are creamy, flavorful and made lighter by using Greek yogurt, less potato and a whole head of cauliflower. They make a comforting, lower-calorie side dish for holiday dinners or weeknight meals.
Mashed potatoes have long been a classic side at family gatherings—served with turkey at Thanksgiving or alongside ham at Christmas. Potatoes sometimes get labeled “unhealthy” because of their carbohydrate content, but preparation matters. This version reduces the potato amount and blends in a full head of cauliflower for extra vegetables and fewer carbs, while Greek yogurt adds protein and a rich creaminess. If you prefer an even lower-carb option, you can make mashed cauliflower on its own.
Why You’ll Love This Recipe
- Healthier than traditional mashed potatoes but still incredibly creamy and satisfying.
- A whole head of cauliflower is hidden in the mix—you won’t miss it.
- Made in one pot and ready in about 30–35 minutes.
- Versatile: ideal for Thanksgiving, Christmas or any weeknight dinner.
Ingredients You’ll Need
- Potatoes – Yukon Golds are recommended for their naturally buttery texture and color, though russets work as well.
- Cauliflower – One large head, broken into florets, adds nutrition and helps reduce the potato portion.
- Plain Greek yogurt – Replaces higher-fat ingredients like sour cream or cream cheese and adds protein for a creamy finish.
- Milk – Use unsweetened almond milk, skim milk or your preferred milk to thin the mash while keeping calories lower.
- Low-sodium chicken broth – Adds flavor and lets you use less milk or cream; vegetable broth works as a substitute.
- Butter – A small amount (or vegan butter) gives the potatoes a classic, comforting flavor.
- Seasonings – Garlic powder (or minced garlic), salt and black pepper.
- Fresh herbs – Optional garnish such as thyme, chives, parsley, rosemary or sage.
How to Make Healthy Mashed Potatoes
- Prep the vegetables. Peel and cut the potatoes into roughly 2-inch chunks. Break the cauliflower into florets and set aside.
- Boil the potatoes. Place only the potatoes in a large pot of salted water and bring to a boil. Reduce heat to medium-low, cover and simmer for about 15 minutes.
- Add the cauliflower. Add the cauliflower florets to the pot and simmer an additional 8–9 minutes, until both potatoes and cauliflower are tender and easily pierced with a fork.
- Drain and combine. Drain the vegetables and return them to the pot. Add milk, Greek yogurt, chicken broth, butter, garlic powder, salt and pepper.
- Mash to your preferred texture. Use a potato masher for a rustic texture or an electric hand mixer for ultra-fluffy, smooth mashed potatoes. Adjust milk or broth for desired creaminess.
- Finish and serve. Taste and adjust seasoning, then transfer to a serving bowl and garnish with fresh thyme and chopped chives. Serve hot.
