- Once the potatoes are tender, drain and mash them with gusto. Add milk, butter, and cheese if you like things extra creamy. Pretend you’re on a cooking show if it helps.
- Mix in the cooked lentils. Stir until combined, but don’t overdo it—nobody wants potato glue.
- Taste for salt and pepper. Adjust if your taste buds say so. A little garlic powder never hurts, either.
- Serve these mashed potatoes hot. Expect some “oohs” and “aahs” from around the table.

Frequently Asked Questions
Creamy mashed potatoes aren’t just about skill—they take a bit of luck, too. Lentils bring new flavors and protein, but you don’t want anyone at the table wondering who messed with the taters. Here’s what people usually ask (and what you might wish you’d known sooner):
How can I achieve the ultimate creaminess in my Thanksgiving mash without it going full soup-mode?
Don’t drown your spuds. Add warm milk or cream slowly and listen to your potatoes—they’ll tell you when enough is enough.
Use real butter and mash while the potatoes are still hot for extra creaminess. Starchy potatoes like Yukon Gold or Russet work best, and the food processor? Skip it unless you like glue. There are more ultra-creamy tips out there if you want to nerd out.
Are lentils the secret weapon for reinventing my grandma’s classic mashed potatoes?
Lentils add a subtle earthy flavor and give your mash a protein boost. They make mashed potatoes more filling, and your vegan cousin might actually smile for once.
Honestly, using lentils isn’t as wild as it sounds—people have been doing it, especially around the holidays. There are plenty of modern recipes out there to prove it.
Can I sneakily incorporate lentils into my mash without my kids staging a dinner table revolt?
Yes, sneaking in lentils is totally possible. Mash them smooth, mix them right in, or use red lentils so the color blends in. Just don’t overdo it. A little cheese or butter on top usually keeps suspicious eyes happy.
Plenty of families have made lentil mashed potatoes kid-approved—so you’re not alone.
What’s Martha’s mystical mashed potato ingredient, or is that level of yum strictly hush-hush?
Martha Stewart’s been known to toss in a pinch of nutmeg, cream cheese, or even sour cream. Nobody’s keeping secrets here—steal her tricks if you want.
That little something extra can turn plain into “please pass more.” If you’re feeling bold, roast a clove of garlic and mash it in. Instant upgrade, trust me.
