This is a creamy roasted red pepper pasta made with red lentil pasta and a blended cashew-pepper sauce. It comes together in about 40 minutes, uses mostly pantry staples, and happens to be naturally gluten-free and vegan. That combination of speed and substance is the real reason to make it.
The short version of why this works
Two things carry this dish. First, soaking the raw cashews before blending — even a 30-minute soak in hot water — is what gives the sauce its smooth, pourable consistency instead of a grainy one. Skip or shorten the soak and the texture suffers noticeably. Second, the smoked paprika goes into the sauce before blending, not sprinkled on top at the end. Blending it in distributes the smokiness evenly and keeps the flavor from tasting like an afterthought. Everything else — the garlic, the nutritional yeast, the almond milk — is doing supporting work around those two decisions.
About the ingredients
- Red lentil pasta: Most large grocery stores carry it now, usually near the regular pasta or in the natural foods aisle. Fusilli or penne work best here because the ridges hold the thick sauce. Avoid overcooking it — lentil pasta goes from al dente to mushy faster than wheat pasta, so start checking it a minute before the package says.
- Nutritional yeast: Adds a savory, slightly cheesy depth that rounds out the sauce. If you don’t have it, the dish still works — just taste and adjust salt. It’s worth keeping a bag on hand if you cook plant-based regularly.
- Roasted red peppers: Jarred peppers are a completely legitimate shortcut here and save real time. Drain them well before blending or the sauce can turn watery.
- Almond milk: Unsweetened only. Oat milk or soy milk work as direct swaps — just make sure whichever you use is also unsweetened and unflavored.
Make-ahead notes
The sauce keeps well in a sealed jar in the fridge for up to 4 days — make a double batch and use the extra as a sauce for grain bowls or a dip for raw vegetables. Cooked lentil pasta is best eaten the day it’s made; it tends to clump and absorb liquid as it sits, so if you’re planning ahead, store the sauce and pasta separately and combine them when reheating. To reheat, warm the sauce in a saucepan over low heat with a splash of water or plant milk to loosen it, then toss in the pasta. The assembled dish can be frozen, though the pasta texture will soften after thawing — freeze in a single airtight container for up to 6 weeks and reheat straight from frozen over low heat, stirring frequently.
What can go wrong
- Sauce is gritty or grainy: The cashews weren’t soaked long enough, or your blender isn’t powerful enough for a short soak. Use boiling water and soak at least 30 minutes, or up to 2 hours in cold water. Blend on high for a full 60 seconds.
- Sauce is too thick to coat the pasta: Add the reserved pasta cooking water a tablespoon at a time while tossing — the starch in it helps the sauce cling and loosens it without diluting the flavor.
- Pasta clumps together before the sauce is ready: Toss the drained pasta with a small drizzle of olive oil immediately after draining if there’s any delay before combining with the sauce.
- Sauce tastes flat: This usually means it needs more salt or more nutritional yeast, not more pepper or paprika. Taste the sauce before it hits the pasta and adjust — it should taste slightly over-seasoned on its own because the pasta will dilute it.
- Fresh basil garnish wilts immediately: Add it right before serving, not while the pasta is still steaming hot. Skip the garnish entirely if you’re serving straight from the pan — not worth the extra dish.
Creamy Roasted Red Pepper Lentil Pasta
Equipment
- High-speed blender
- Large pot
- Skillet
- Colander
- Chef's knife
Ingredients
- 12 oz red lentil pasta choose fusilli or penne for better sauce adhesion
- 1 tbsp extra-virgin olive oil cold-pressed preferred
- 3 cloves garlic minced
- 1 cup roasted red peppers drained if using jarred, or home-roasted for depth
- ½ cup raw cashews soaked in hot water for at least 15 minutes or overnight
- ¾ cup unsweetened almond milk or other neutral plant milk
- 1 tbsp nutritional yeast adds umami and cheesiness
- ½ tsp smoked paprika adds depth and smokiness
- ½ tsp sea salt to taste
- ¼ tsp fresh ground black pepper
- ¼ cup fresh basil chopped, for garnish
Instructions
- Bring a large pot of salted water to a boil. Add red lentil pasta and cook according to package instructions, usually about 7–9 minutes. Stir occasionally to prevent sticking. Drain and set aside.
- While the pasta cooks, make the sauce. In a skillet, heat olive oil over medium heat. Sauté minced garlic for 1–2 minutes, until fragrant but not browned.
- Add sautéed garlic, roasted red peppers, soaked cashews, almond milk, nutritional yeast, smoked paprika, salt, and pepper to a high-speed blender. Blend until silky smooth, about 60–90 seconds. Taste and adjust seasoning.
- Return the drained pasta to the pot over low heat. Pour the sauce over the pasta and stir gently to coat. Warm for 2–3 minutes, stirring occasionally, until the sauce thickens slightly and clings to pasta.
- Serve immediately, garnished with fresh chopped basil and a sprinkle of extra nutritional yeast or crushed red pepper if desired.
Notes
- To soak cashews quickly, cover them with hot water and let sit for 15 minutes before draining.
- For extra veggies, stir in sautéed spinach, zucchini, or mushrooms before adding the sauce.
- Jarred roasted red peppers are a time-saver, but homemade brings smokier depth.

Frequently asked questions
Can I use regular wheat pasta instead of red lentil pasta?
Yes, any pasta shape works here. The sauce is the star, so the swap is straightforward — just use whatever you have. Keep in mind you’ll lose the extra protein and fiber that red lentil pasta provides, but the dish will still taste great.
Do I have to soak the cashews, or can I just blend them dry?
You need to soak them for a smooth sauce — blending dry cashews leaves the sauce grainy. If you’re short on time, cover them with boiling water for 20 to 30 minutes; that’s enough to soften them adequately for most blenders.
Is this dish actually filling enough as a main?
Yes — red lentil pasta has significantly more protein and fiber than regular pasta, and the cashew sauce adds fat, so the meal is genuinely satisfying. If you’re feeding people with bigger appetites, stir in a can of drained white beans or add a side of crusty bread.
Can I make this without a high-speed blender?
A standard blender works if you soak the cashews for the full time and blend in longer bursts. A food processor is a last resort — the sauce will be less smooth, but still tasty. Avoid using an immersion blender; it won’t get the cashews fine enough.
