Steps

Before you start
  • Rinse the brown rice and black lentils separately under cold water
  • Measure out the vegetable broth before you begin
  • Wash the mustard greens thoroughly and remove any thick center stems
  1. Sauté aromatics

    • Heat the olive oil in a medium saucepan (2–3 quart) over medium heat.
    • Add the minced garlic and cook for about 1 minute, stirring constantly, until fragrant but not browned.
    • You want the garlic to just begin to soften and release its aroma.

    Ready when: Garlic is fragrant and light golden

    Tip: Don't let garlic brown or it will taste bitter.

  2. Add rice and lentils

    • Stir in the rinsed brown rice and black lentils, mixing them well with the garlic and oil.
    • Toast them together for 2–3 minutes, stirring occasionally.
    • This step helps develop a nutty, deeper flavor.

    Ready when: Rice and lentils appear slightly dry and smell toasty

    Tip: Toasting builds flavor and helps the grains cook more evenly.

  3. Add broth and seasonings

    • Pour in the vegetable broth, then add kosher salt (about ½ teaspoon to start), freshly ground black pepper, and the red pepper flakes if using.
    • Stir well to combine and ensure nothing is sticking to the pan bottom.

    Ready when: Liquid is evenly distributed

    Tip: Stir the bottom to prevent sticking before the liquid simmers.

  4. Bring to a boil

    • Increase the heat to medium-high and bring the mixture to a rolling boil, about 3–4 minutes.
    • You should see large bubbles breaking the surface continuously.
    + Show details

    Ready when: Large bubbles break the surface, steam rises

  5. Reduce heat and cover

    • Once boiling, reduce the heat to medium-low.
    • Cover the pan with a tight-fitting lid and let it simmer gently.
    • Set a timer for 25 minutes.
    + Show details

    Tip: Keep the lid on—don't peek—to maintain steady heat and moisture.

  6. Stir in mustard greens

    • After 25 minutes, carefully remove the lid (watch for steam) and stir in the chopped mustard greens, pushing them down into the mixture.
    • The greens will wilt and reduce in volume.
    • Replace the lid.
    + Show details

    Ready when: Greens are pushed down into the rice

    Tip: Add greens near the end so they stay slightly tender and don't become mushy.

  7. Final simmer

    • Cook covered for another 2–3 minutes, until the mustard greens are fully wilted and tender.
    • The rice should be tender, the lentils cooked through (not mushy), and most of the liquid absorbed.
    + Show details

    Ready when: Greens are completely wilted, rice is tender to the bite, lentils are cooked

    Tip: If liquid remains, cook uncovered for 1–2 minutes more to allow it to evaporate.

  8. Rest and season

    • Remove from heat and let the pan sit, covered, for 5 minutes.
    • This allows the grains to finish absorbing any remaining moisture and the flavors to settle.
    • Taste and adjust salt and pepper as needed.
    + Show details

    Ready when: No steam escapes when lid is removed

    Tip: Seasoning after cooking allows you to taste and balance the flavors to your preference.

Good to know

Tips
  • Rinsing the rice and lentils removes excess starch and helps them cook more evenly without clumping.
  • The mustard greens add a subtle peppery bite that balances the nuttiness of the brown rice and earthiness of the lentils—don't skip them.
  • This dish is naturally vegan and gluten-free; it's excellent served warm or at room temperature as a hearty side or grain bowl.
  • For extra richness, stir in a pat of butter or a drizzle of good olive oil just before serving.
Make ahead

You can prepare and chop all ingredients up to 1 day ahead. Store the rice mixture, covered, in the refrigerator for up to 3 days. Reheat gently on the stovetop over medium-low heat, stirring occasionally and adding a splash of broth if it seems dry.

Storage & reheating

Room temperature: up to 2 hours in an airtight container. Refrigerator: up to 3 days in a covered container. Freezer: up to 2 months in a freezer bag or airtight container. Thaw overnight in the refrigerator and reheat on the stovetop with a splash of broth, stirring often until warmed through.

Substitutions
  • brown rice → wild rice, farro, or long-grain white rice. Adjust the liquid ratio slightly if using white rice (use 3¼ cups broth instead of 3½) as it cooks faster.
  • black lentils (also called beluga lentils) → green lentils or red lentils. Green lentils hold their shape well; red lentils cook faster and will be softer. Adjust cooking time accordingly.
  • fresh mustard greens → collard greens, kale, or spinach. Collards and kale are heartier and can handle the same cooking time. Spinach will wilt very quickly, so add it in the last minute.
  • vegetable broth → chicken broth or a light seafood broth. Either will add deeper flavor; use the same quantity.
