I’ll be honest, I made this the first time because I had a punnet of cherry tomatoes going soft and half a bag of green lentils with nowhere to go.
It turned out to be one of those meals I keep coming back to. The tomatoes blister in the oven and go almost jammy. They don’t need much help after that.
Lentils do two things here: they stretch the pasta so you need less of it, and they add a quiet, earthy backbone — much like in a hearty lentil veggie skillet — that makes the dish feel filling without being heavy.
This is real food doing its thing. One pot, 40 minutes, and a dinner that holds up to a long day.

Ingredient Notes
- cherry tomatoes: Use ripe cherry or grape tomatoes for the best concentrated flavor after roasting. Roma tomatoes cut in half also work well.
- green lentils: Green or French Puy lentils hold their shape best here. Red lentils go mushy and aren’t a good swap for this texture.
- short pasta: Rigatoni, penne, or fusilli all work. You want a shape that traps the sauce and lentils in each bite.
- garlic: Whole cloves roast alongside the tomatoes and turn sweet and soft. Mince them into the sauce or just smash them in.
- olive oil: Use a decent extra virgin for roasting. It becomes part of the sauce, so it matters more than in most recipes.
- Parmesan: Optional but worth it. A light grating over the top adds salt and a mild nutty note. Skip it to keep the dish vegan.
- fresh basil: Stir in right at the end. Heat kills the bright flavor, so add it off the stove.
Roasted Tomato Lentil Pasta
Ingredients
Method
- Heat the oven to 200 C / 390 F.
- Place halved cherry tomatoes and unpeeled garlic cloves on a rimmed sheet pan.
- Drizzle with 3 tbsp olive oil, sprinkle with salt, pepper, dried oregano, and chili flakes if using.
- Toss to coat, then spread in a single layer cut-side up.
- Roast for 25 to 30 minutes until the tomatoes are blistered and the edges are beginning to char.
- While the tomatoes roast, add rinsed green lentils to a saucepan with 750 ml of vegetable broth or salted water.
- Bring to a boil, then reduce to a steady simmer and cook uncovered for 18 to 20 minutes until tender but still holding their shape.
- Drain any excess liquid and set lentils aside.
- Bring a large pot of well-salted water to a boil.
- Cook pasta according to package directions until al dente.
- Before draining, scoop out 120 ml of pasta cooking water and set it aside.
- Drain the pasta.
- Remove the sheet pan from the oven. Squeeze the soft roasted garlic from its skins directly onto the pan and mash roughly into the tomatoes with a wooden spoon.
- Drizzle with the remaining 1 tbsp olive oil and stir into a rough, chunky sauce.
- Add the drained lentils and drained pasta to the pan or a large serving bowl.
- Pour the roasted tomato mixture over the top and toss well, adding splashes of reserved pasta water to loosen the sauce to your liking.
- Taste and adjust salt. Scatter torn basil over the top and serve immediately, with Parmesan if using.
Notes
Tips for Success
- Spread tomatoes in a single layer on the sheet pan so they roast, not steam.
- Cook lentils in salted water until just tender, about 20 minutes, then drain before adding.
- Reserve 120 ml of pasta cooking water to loosen the sauce when tossing everything together.
- Roast garlic cloves unpeeled alongside the tomatoes, then squeeze the soft flesh directly into the pan.
- Toss pasta with the tomato-lentil mixture off the heat to keep the herbs fresh and the sauce bright.
Variations
- Add a pinch of chili flakes and smoked paprika to the tomatoes before roasting for a smoky heat.
- Stir in a large handful of baby spinach when tossing hot pasta for extra greens.
- Use roasted red peppers alongside the tomatoes for a sweeter, deeper sauce base.
Storage and Reheating
Store leftovers in an airtight container in the fridge for up to 3 days. The lentils absorb more liquid as they sit, so the pasta thickens overnight.
Reheat on the stovetop over medium-low heat with a splash of water or broth to loosen the sauce. Stir often so nothing catches on the bottom.
This dish doesn’t freeze well because the pasta goes soft after thawing. Freeze the roasted tomato and lentil base separately if you want a head start for later in the week.
Serving Suggestions
A simple green salad with lemon dressing, something like a roasted beet and arugula bowl, sits well alongside this, cutting through the richness of the olive oil and tomatoes.
For a heartier table, serve with thick slices of sourdough or a good crusty bread to mop up the sauce at the bottom of the bowl.
A glass of dry white wine, a light Pinot Grigio or Vermentino, works nicely here. If you’re skipping wine, sparkling water with a slice of lemon keeps the meal feeling fresh.
FAQ
Why are my roasted tomatoes watery instead of jammy?
The pan is likely too crowded. When tomatoes overlap, they steam rather than roast and release too much liquid. Spread them in a single layer with space between each one.
Can I use canned lentils instead of cooking dry ones for this pasta?
Yes, one 400 g can of drained green or brown lentils works. Rinse them well first and add them when you would normally add the cooked lentils.
Can I roast the tomatoes the night before and build the pasta the next day?
Yes, and it actually improves the flavor. Store the roasted tomatoes and garlic in a covered container in the fridge for up to 2 days, then reheat in a pan before tossing with fresh pasta.
What pasta shape works best with lentils and roasted tomatoes?
Short ridged shapes like rigatoni or penne are best because lentils nestle into the tubes and the ridges hold the sauce. Long pasta like spaghetti tends to separate from the lentils.
Is roasted tomato lentil pasta gluten-free?
Not with standard wheat pasta, but it’s easy to swap in your preferred gluten-free pasta, and if you want a gluten-free creamy tomato base as a reference point, brown rice or chickpea pasta both hold up well with the thick tomato-lentil sauce.
How is this different from a standard tomato pasta sauce?
The lentils add protein and a slightly earthy texture that a plain tomato sauce doesn’t have, making it a full meal without meat. Roasting concentrates the tomato flavor more than simmering does.
