Introduction

This Quinoa, Spinach and Lentil Casserole is a nourishing plant-based meal combining quinoa, red lentils and spinach with warming spices, creamy plant-based cream and a layer of melted vegan cheese.

Quinoa and red lentils make an excellent combination for a substantial meat-free meal, providing plant-based protein, fibre and complex carbohydrates. Spinach adds a generous portion of vegetables along with folate, vitamin K and carotenoids, while paprika, cumin, coriander and turmeric create a warm, savoury flavour.

Prepared with certified gluten-free quinoa and lentils and checked gluten-free plant cream, vegan cheese and spices, this casserole makes a satisfying gluten-free vegan and gluten-free vegetarian dinner. It is naturally egg-free and dairy-free when made with fully plant-based ingredients.

Benefits of All the Ingredients

Quinoa

Quinoa provides both carbohydrates and protein and creates a hearty foundation for the casserole.

It contains plant-based protein, dietary fibre and complex carbohydrates, as well as magnesium, phosphorus, manganese, folate and iron.

Quinoa is notable among plant foods because its protein contains all nine essential amino acids, although—as with most plant proteins—the proportions and overall protein density differ from animal-based sources.

Quinoa is naturally gluten-free. For someone with coeliac disease, choose quinoa specifically labelled gluten-free because cross-contact with gluten-containing grains can occur during processing.

Rinsing quinoa thoroughly before cooking also helps remove naturally occurring saponins from its surface, which can otherwise produce a slightly bitter taste.

Red Lentils

Red lentils significantly increase the protein and fibre content of this casserole.

They provide plant-based protein, dietary fibre and complex carbohydrates, along with folate, iron, magnesium, potassium, phosphorus and manganese.

Because red lentils soften considerably during cooking, they also contribute to the casserole's creamy, comforting texture.

Lentils are naturally gluten-free but can experience cross-contact with wheat and other grains during harvesting and processing. For a coeliac-safe recipe, choose certified gluten-free lentils, sort them carefully and rinse before cooking.

Onion

Onion provides a savoury aromatic base that complements the earthy lentils and warming spices.

It contains small amounts of vitamin C, folate and potassium, as well as naturally occurring plant compounds such as quercetin and organosulfur compounds.

Fresh onion is naturally gluten-free and vegan.

Spinach

Using a generous amount of spinach adds vegetables and valuable micronutrients without overpowering the casserole.

Spinach provides vitamin K, folate, provitamin A carotenoids, vitamin C and magnesium. It also contains the carotenoids lutein and zeaxanthin.

Spinach contributes some iron as well, although plant-based non-haem iron is absorbed differently from haem iron found in animal foods.

Frozen spinach is a convenient whole-food ingredient and retains many of the nutrients found in fresh spinach.

Plain frozen spinach is naturally gluten-free, but flavoured or prepared spinach products should be checked for additional ingredients.

Ground Paprika

Paprika adds mild pepper flavour and colour.

Made from dried peppers, paprika contains naturally occurring carotenoid pigments and other plant compounds.

Pure paprika is naturally gluten-free, although gluten-free-labelled spices are preferable when cross-contact during processing is a concern.

Ground Cumin

Cumin provides a warm, earthy flavour that works particularly well with lentils and quinoa.

It contains naturally occurring aromatic plant compounds and provides some iron, although the amount used per serving is relatively small.

Pure cumin is naturally gluten-free.

Ground Coriander

Ground coriander adds a subtle citrusy, earthy note that complements cumin and turmeric.

Coriander seeds contain naturally occurring aromatic compounds and small amounts of minerals.

Choose pure or gluten-free-labelled ground coriander when preparing the casserole for someone who needs strict gluten avoidance.

Garlic Powder

Garlic powder provides concentrated savoury flavour and distributes easily throughout the casserole.

Garlic naturally contains organosulfur compounds, although the composition differs somewhat between fresh and dried garlic.

Pure garlic powder is naturally gluten-free, but seasoning products can be exposed to cross-contact during manufacturing, so check the label when preparing a coeliac-safe meal.

Ground Turmeric

Turmeric provides a warm golden colour and an earthy flavour.

Its characteristic yellow-orange colour comes largely from naturally occurring compounds called curcuminoids, including curcumin.

The relatively small quantity used here is primarily valuable for flavour and colour rather than providing a large nutritional dose.

Pure turmeric is naturally gluten-free.

Plant-Based Cream

Plant-based cream creates a creamy consistency while keeping the casserole completely dairy-free and vegan.

Its nutritional profile varies considerably depending on whether it is made from soy, oats, coconut, cashews or another plant source.

Soy-based options can provide additional protein, while coconut-based creams are generally higher in saturated fat.

Choose an unsweetened variety where possible. For a gluten-free casserole, check the packaging carefully and choose a product labelled gluten-free, particularly when using an oat-based cream.

Vegan Cheese

Vegan cheese adds a creamy, savoury topping and helps create the comforting baked-casserole texture.

The nutritional value varies considerably between products. Some are based primarily on coconut oil and starch, while others use nuts, soy, legumes or other plant ingredients and may provide more protein.

Coconut-oil-based vegan cheeses can be relatively high in saturated fat, so the ingredient list and nutrition label are worth comparing if nutritional quality is a priority.

For a completely gluten-free vegan casserole, choose a vegan cheese specifically labelled gluten-free, as ingredients and manufacturing processes vary between brands.
