Background and objectives More than 2 billion people suffer with malnutrition arising from dietary protein and micronutrients deficiencies. To enhance the dietary nutrient quality, the current study used two largely grown varieties of finger millet, pearl millet, pigeonpea, and chickpea to evaluate the effect of millet–legume blends for their enhanced protein digestibility, amino acid profiles, and essential micronutrients. Findings Our study revealed the presence of significant levels of proteins (6.3%–22.3%), essential amino acids, and micronutrients (Fe: 2.6–8.5 mg; Zn: 2–5.5 mg; Ca: 22‐450 mg in 100 g) in these varieties. When specific millets combined with legumes in 3:1 proportion, significantly enhanced nutritional value of food by providing a balanced amino acid with good protein digestibility, and high levels of iron (7.58 mg) and zinc (4.96 mg) with 100 g of pearl millet and calcium (400.57 mg) with 100 g of finger millet. Conclusions Pigeonpea and chickpea have a good level of proteins with essential amino acids except methionine and cysteine, whereas millet had balanced amino acid including methionine and cysteine (50% higher) and much higher levels of micronutrients (Fe, Zn and Ca). Therefore, specific millets and legumes combination complemented higher levels of micronutrients in addition to complete proteins to support comprehensive human nutrition. Significance and novelty This study opens prospects for selecting complementary nutrient‐dense varieties for household consumption. Industries can explore these product developments significantly to reduce malnutrition if consumed adequately, which is not possible with polished rice, refined wheat flour or maize even if it is combined with legumes.
