Caesar Salad with Baby Potatoes & Lentils
Roasted baby potatoes with garlic and Parmesan replace croutons. Avocado, cherry tomatoes, and canned lentils pile on top. The dressing is yogurt, mayonnaise, mustard, and lemon — no raw egg, no anchovy, five seconds to stir.
One bowl, 693 calories with 15 grams of fiber split across lentils, avocado, and potatoes. A randomized crossover trial found that adding lentils to potatoes reduced the blood sugar response by roughly a third. The lentils you added for texture are quietly moderating the potatoes.
Ingredients
- garlic 1 clove
- baby potatoes 0.5 pound
- olive oil 1 tablespoon
- grated cheese 1 ounce
- avocado 0.5
- cherry tomatoes 8
- lentils, canned 2 ounces
- yogurt, nonfat 1 tablespoon
- mayonnaise 0.5 tablespoon
- lemon juice 1 squeeze
- yellow mustard 1 teaspoon
- iceberg lettuce, shredded 1 handful
Method
-
Preheat the oven to 400°F (200°C).
-
Crush the garlic. Halve the baby potatoes.
-
Line a baking sheet with parchment paper and spread the potatoes out in a single layer. Toss with oil, half of the garlic, half of the cheese and salt and pepper.
-
Roast for 20 minutes, until tender and golden brown.
-
Slice the avocado. Halve the cherry tomatoes and rinse the lentils in a colander. Let drain well.
-
Make the dressing: mix the yogurt, mayonnaise, lemon juice, mustard and the remaining garlic. Season lightly with salt and pepper.
-
Place the lettuce on a plate. Top with the roasted potatoes, avocado, cherry tomatoes, lentils, and the remaining cheese. Drizzle with the dressing and season to taste.
Mash a few slices of avocado directly into the dressing before drizzling. It thickens the yogurt-mayo base into something closer to a traditional creamy Caesar, and the fat helps carry the mustard and garlic flavor across the whole bowl.
A 2018 randomized crossover trial tested what happens when lentils and potatoes share a plate. Replacing half the potato carbohydrates with lentils cut the blood sugar response by 34% and the insulin response by 35%. The insulin drop was specific to potatoes — when lentils were paired with rice instead, the insulin effect disappeared. This recipe uses a smaller proportion of lentils than the study tested (roughly 16% of available carbs vs. the study’s 50%), so the effect is proportionally smaller, but the same mechanisms engage at any ratio: resistant starch, protein-starch interaction, and phenolic compounds that slow starch digestion.

Does it matter which type of lentil I use?
The Moravek 2018 study tested three varieties: large green, small green, and split red. All three reduced the blood sugar response by the same amount. Split red lentils had half the fiber of the green varieties but still produced the same glucose reduction, which means fiber alone does not explain the effect. Use whatever canned lentils you can find.
Can this salad work as a full meal at 21 grams of protein?
It depends on your daily target. At 21 grams, this salad covers a moderate portion but falls below the 30–40g range that some crossover research associates with maximizing per-meal muscle protein synthesis. If you want more, add grilled chicken breast or a hard-boiled egg without changing the base recipe.
Why yogurt and mayo instead of traditional Caesar dressing?
Traditional Caesar uses raw egg yolk and anchovies as the emulsifier and flavor base. This version swaps in nonfat yogurt for tang and body, a half tablespoon of mayo for richness, and mustard for the savory bite. The result is a lighter dressing that still coats the potatoes and lettuce the way a Caesar should.
Do the lentils actually lower blood sugar in this recipe, or is the portion too small?
The Moravek study tested a 50:50 carbohydrate split between potatoes and lentils. This recipe’s ratio is closer to 84:16 (about 37g of available carbs from potatoes and 7g from lentils). The 34% reduction applies to the study’s higher lentil dose. At this recipe’s proportion, the effect is smaller, but the mechanisms (resistant starch, protein-starch interaction, enzyme inhibition by phenolic compounds) engage at any ratio. The direction holds. The magnitude scales down.
