Pair with Spiced Chickpeas Fire-Roasted Tomatoes and Tuscan Kale Salad with Lemon Tahini Dressing for a delicious, complete meal.
My kids took one look and called them purple cow potatoes.
Boil, cool, smash, and pan-fry with garlic and olive oil. Cooling first builds resistant starch — better for your gut, better for blood sugar, and they hold together beautifully in the pan. Make a big batch and pan-fry only what you need all week.

Ingredients
- Purple sweet potatoes, as many as desired, whole and unpeeled
- Garlic, 2-3 cloves per serving, minced
- Olive oil, 1-2 tbsp per serving
- Sea salt + pepper, to taste
Instructions
-
Boil
- Scrub sweet potatoes, trim ends, place whole and unpeeled in large pot.
- Cover with cold water.
- Bring to a boil and cook until a fork slides through easily with no resistance — about 20-30 minutes.
-
Cool
- Drain and refrigerate uncovered until fully cool — at least a few hours or overnight. Keeps up to 5 days.
-
Smash and pan fry
- Cut large potatoes in half for a single serving portion.
- Heat olive oil and garlic in a cast iron pan over medium heat.
- Place potato in pan, press gently with a spatula to flatten slightly keeping skin intact.
- Cook 3-4 minutes per side. Season with sea salt and black pepper.
- Pan fry to your preference — a shorter cook keeps them tender, longer gives you more golden edges.

Why Purple Sweet Potatoes:
- Higher in antioxidants than orange sweet potatoes — anthocyanins (the purple pigment) are linked to reduced inflammation, brain health, and heart protection
- Naturally sweet with a lower glycemic impact than regular potatoes
- Good source of fiber, vitamin C, potassium, and B6
- The skin holds most of the nutrition — smashing keeps every bit intact
Swap It + Smart Tips
- No cast iron? A stainless steel or nonstick pan works — cast iron just gives you the best contact and heat retention
- No olive oil? Use avocado oil for a higher smoke point
- Want crispy edges? Cook longer on each side and resist moving them — let the crust form undisturbed
Meal Prep Tip
Boil a big batch at the start of the week and refrigerate whole and unpeeled. Smash and pan-fry only what you need at each meal. The cooling process actually improves the nutritional profile — so your meal prep is doing double duty. They keep in the fridge for up to 5 days and pair beautifully with almost anything.
Why It Matters
For You:
- Anthocyanins in purple sweet potatoes are among the most potent antioxidants in any whole food — they fight inflammation and support brain and heart health
- Cooling cooked potatoes increases resistant starch, which feeds beneficial gut bacteria, stabilizes blood sugar, and supports lasting fullness
- Keeping the skin on means more fiber, more nutrients, and nothing wasted
- A natural source of potassium, vitamin C, B6, and complex carbohydrates that fuel your body without a blood sugar spike
For the Planet:
- Sweet potatoes are one of the most resource-efficient crops on earth — low water use, minimal inputs, and high yield
- Buying whole, unprocessed produce means zero packaging waste
- Cooking a big batch at once reduces energy use throughout the week
- Plant-based sides like this one reduce your meal’s overall environmental footprint without sacrificing satisfaction
Pro Tip
Don’t skip the cooling step. Beyond the resistant starch benefits, cool potatoes hold their shape when smashed and develop a better texture in the pan. Warm potatoes will fall apart. Cold potatoes smash beautifully.
