Baby Potato Salad with Bell Pepper & Lentils
Crispy roasted baby potatoes, straight from a 390°F oven, tossed with cold lentils, diced bell pepper, and a sharp mustard-balsamic dressing on a bed of mixed greens.
One baking sheet, 20 minutes, and almost no prep. 502 kcal with 11g of fiber from the potato-lentil base — roughly 37% of what most guidelines suggest per day, packed into one bowl.
Ingredients
- baby potatoes 0.5 pound
- garlic 1 clove
- olive oil 1.5 tablespoon
- lentils, canned 4 ounces
- bell pepper 1
- yellow mustard 0.5 teaspoon
- balsamic vinegar 0.5 tablespoon
- mixed salad 1 handful
Method
-
Preheat the oven to 390°F (200°C).
-
Halve the baby potatoes and crush the garlic clove. In a bowl, mix the baby potatoes with half of the oil, garlic and some salt and pepper. Place the baby potatoes on a baking sheet lined with parchment paper and put them in the oven. Bake the baby potatoes for 17 minutes until they are golden brown and crispy.
-
In the meantime, rinse the lentils in a colander with cold water and let them drain. Dice the bell pepper.
-
Make a dressing with the other half of the oil, mustard and balsamic vinegar. Whisk them together in a small bowl.
-
Spread the mixed salad over a platter. Add the bell pepper, lentils and baby potatoes. Drizzle the dressing over the salad and serve.
Make this salad ahead and let it sit in the fridge. Roasted potatoes form resistant starch as they cool, a type of starch your body processes more slowly. The lentils and dressing absorb flavor overnight, and the whole salad holds up beautifully cold the next day.
When potatoes are baked and then cooled, their starch crystallizes into a structure called resistant starch that resists digestion in the upper gut. Patterson and colleagues measured the effect in 30 women: chilled potatoes produced 17.7% lower insulin and 35.1% lower GIP compared to hot boiled potatoes. The study used five-day refrigeration at 4°C, so your overnight meal prep won’t match those numbers exactly, but the process begins as soon as potatoes start cooling.
Patterson et al. 2019, Nutrients · DOIWhy This Works
Behind this recipe
Can I make this salad ahead of time?
Yes, and it genuinely improves. Roasted potatoes form more resistant starch as they cool, which research links to a lower insulin and GIP response compared to hot potatoes. The lentils and dressing absorb flavor overnight. Make it in the evening and grab it cold for lunch the next day.
Is 14g of protein enough for a full meal?
14g is moderate for a main. This salad is primarily a fiber-and-carb meal. If you want more protein, add grilled chicken breast, a boiled egg, crumbled feta, or double the lentils. The lentils provide plant-based protein alongside slow-digesting carbs, but they are not the protein powerhouse here.
Why pair lentils with potatoes?
Beyond taste and texture: research by Moravek and colleagues found that adding lentils to a potato meal reduced blood glucose by 34% and insulin by 35% compared to potatoes alone. The effect was specific to the lentil-potato pairing and didn’t replicate with rice. Something about how lentil starch, protein, and flavonols interact with potato starch slows digestion in ways fiber alone doesn’t explain.

Yes. Cook them for 20–25 minutes until tender but not mushy, then drain and cool before adding to the salad. Canned lentils keep this recipe under 20 minutes total. Either way, rinse them well — the liquid in the can tastes starchy and muddies the dressing.
