Umbrian Lentils with Garlic and Rosemary
A rustic Italian bean side dish that celebrates the delicate, earthy flavor of small green lentils cooked gently with fragrant rosemary, garlic, and quality olive oil. This Umbrian classic hails from the Umbria region of central Italy, where Castelluccio lentils are prized for their tender texture and nutty taste. The lentils are toasted briefly before simmering in vegetable broth, emerging creamy yet with each grain intact. Serve warm alongside roasted meats and vegetables, or let cool and toss with vinaigrette for a rustic salad.

Steps
Before you start
- Rinse the lentils in a fine-mesh strainer to remove any dust or debris
- Gather fresh rosemary sprigs and peel the garlic cloves
- Use quality extra-virgin olive oil for the best flavor—this recipe showcases it
- Have your vegetable broth at hand, room temperature or warm
Rinse and prepare lentils
- Place the lentils in a fine-mesh strainer and rinse under cool running water, rubbing gently between your fingers.
- Pick through to remove any debris or damaged lentils, then drain well.
- Peel the garlic cloves and lightly smash them with the side of a chef's knife to crack them open—this releases oils and flavor without mincing.

Ready when: Lentils are clean and debris-free; garlic cloves are cracked open
Tip: Don't skip rinsing—even small debris can hide in lentil packages. Smashing (rather than mincing) the garlic releases flavor gently without burning easily.
Warm oil and garlic
- Heat the extra-virgin olive oil in a medium saucepan (3–4 quart) over medium heat.
- Once the oil is shimmering, add the smashed garlic cloves and a pinch of red pepper flakes if using.
- Warm for 2–3 minutes, stirring occasionally, until the garlic is fragrant and takes on a very light golden color.
- Do not allow it to brown—you want the garlic to gently infuse the oil.

Ready when: Garlic is pale golden, fragrant, and releases a gentle aroma
Tip: Brown garlic tastes bitter. Keep heat moderate and watch constantly to prevent this. If garlic starts to darken too quickly, reduce heat immediately.
Toast lentils briefly
- Pour the rinsed lentils into the saucepan and stir continuously for 1–2 minutes.
- This gentle toasting develops their natural nutty flavor and helps them absorb broth without becoming mushy.
- Ensure all lentils are evenly coated with the garlic-infused oil.

Ready when: Lentils are evenly coated with oil and smell toasted and nutty
Add broth and herbs
- Carefully pour in the vegetable broth, stirring gently to combine.
- Add the rosemary sprigs and bay leaf if using.
- Increase heat to medium-high and bring the liquid to a steady simmer, stirring occasionally, which should take about 5 minutes.

Ready when: Liquid is at a rolling simmer
Simmer until tender
- Once simmering, reduce heat to medium-low.
- Simmer uncovered for 25–30 minutes, stirring gently every 5–7 minutes to ensure even cooking and prevent sticking to the bottom.
- The lentils are done when they are tender but still hold their shape—they should not be mushy or falling apart.
- Most of the broth will be absorbed, but a small amount of liquid should remain.
- If lentils are tender before all broth is absorbed, remove from heat; if liquid remains but lentils are still firm, cook 2–3 minutes longer.

Ready when: Lentils are tender but intact; most broth absorbed; slight liquid remaining
Tip: Resist covering the pan—a gentle, uncovered simmer allows steam to escape and prevents overcooking and mushiness. Avoid aggressive stirring, which can break delicate lentils.
Season and rest
- Remove from heat.
- Discard the rosemary sprigs and bay leaf using a slotted spoon.
- Taste the lentils and season generously with sea salt and freshly ground black pepper to your preference.
- Stir gently once more and let the lentils rest, uncovered, for 5 minutes.
- This allows flavors to meld and any remaining broth to be fully absorbed.

Ready when: Lentils are evenly seasoned and rested; ready to serve
Tip: Season near the end of cooking rather than at the start, as salt added early can toughen the lentils' outer skin. This final resting period is crucial for tender, flavorful lentils.
Good to know
Tips
- Lentils from Castelluccio di Norcia in Umbria are prized for their delicate flavor and ability to remain intact during cooking. If you can find them, they're worth seeking out, though good-quality French green lentils are an acceptable substitute.
- Don't stir too often during cooking—gentle stirring every 5–7 minutes prevents sticking without breaking the delicate lentils. Each gentle stir redistributes heat and liquid evenly.
- For deeper, more luxurious flavor, finish the cooked lentils with an extra drizzle of high-quality extra-virgin olive oil and a pinch of fleur de sel just before serving.
- This dish pairs beautifully with roasted meats, polenta, braised greens, or grilled vegetables. It's also excellent at room temperature as part of a composed salad with fresh greens and vinaigrette.
Make ahead
The lentils can be prepared up to 1 day ahead and reheated. Store in an airtight container in the refrigerator. Reheat gently on the stovetop over medium-low heat, stirring occasionally and adding a splash of broth or water if they seem dry.
Storage & reheating
Room temperature: up to 2 hours. Refrigerator: up to 4 days in an airtight container. Freezer: up to 3 months. To reheat, warm in a saucepan over medium-low heat, stirring occasionally and adding a little water or broth if needed, until warmed through.
Substitutions
- small green lentils (Castelluccio di Norcia or Umbrian variety) → French (green) lentils or brown lentils. Castelluccio lentils have a delicate, earthy flavor, but other small green lentil varieties work well. Avoid red or yellow lentils, which break down too easily during cooking.
- vegetable broth → Water or light chicken broth. Plain water lets the lentil and herb flavors shine without competition. Chicken broth adds richness and depth.
- fresh rosemary sprigs → Fresh thyme or a mix of thyme and oregano. Rosemary is traditional in Umbrian cooking, but thyme or oregano offer a different but equally delicious herbal note. Use the same quantity.
- extra-virgin olive oil → Other neutral oil (sunflower, grapeseed) in equal amount. This recipe celebrates olive oil's characteristic fruity, grassy notes, so high-quality extra-virgin oil is ideal. Neutral oil works for cooking but loses the signature flavor.
