This High-Protein Vegan "Marry Me" pasta has become my go-to when I want something comforting, vibrant, and truly satisfying without dairy or meat. I first created this version while testing ways to boost plant protein in a single, make-ahead meal for busy weeks. Using lentil pasta as the base and a silky cashew cream for richness, the dish brings together bold tomato notes, smoky paprika and tender butter beans for heft. The result is the kind of creamy pasta that feels indulgent but fuels you for hours — my partner and I both reach for seconds every time.

I discovered the balance of flavors on a rainy Sunday when I had a jar of sun-dried tomatoes, a bag of cashews, and a half-open packet of lentil pasta. After a few small adjustments — a splash of lemon to brighten, a pinch of smoked paprika for depth, and the inclusion of butter beans for extra protein and texture — the recipe became a stable fixture in my meal-prep rotation. It reheats beautifully, tastes even better the next day, and is endlessly adaptable for allergies or whatever’s in your pantry.

Ingredients

• Lentil pasta (12 oz): Use brown-lentil or red-lentil pasta (12 ounces / about 340 g) for maximum protein and a firm texture that holds sauce. Brands I like: Tolerant Foods or Explore Cuisine. Avoid thin cut spaghetti for a heartier bite; penne, fusilli or radiatori are ideal.
• Cashew cream: 1/4 cup raw cashews, 1/4 cup nutritional yeast, and 2 cups unsweetened soy milk — this creates a silky, savory base. Soak cashews in boiling water to soften for blending; sunflower seeds work as a nut-free option.
• Onions & peppers: Two yellow onions finely sliced and one medium red bell pepper thinly sliced add sweetness and body when gently caramelized. Pick firm peppers with glossy skin for the best texture.
• Sun-dried tomatoes & garlic: About 2 ounces thinly sliced sun-dried tomatoes plus 3 cloves garlic provide umami complexity and aromatic lift. Use tomatoes packed in oil for richer flavor or rehydrate dry-packed ones in hot water.
• Spices & tomato paste: 1.5 tablespoons tomato paste, 1.5 teaspoons cajun spices, and 2 teaspoons smoked paprika deliver depth and a smoky, slightly spicy backbone. Adjust cajun seasoning to taste if you prefer milder heat.
• Butter beans (1.5 cups cooked): Adds creaminess and a big protein boost — use canned or home-cooked butter (lima) beans, drained and rinsed. They hold their shape while blending with the sauce.
• Finishing: 4 cups baby spinach roughly chopped, 1/4 cup fresh parsley finely chopped, and 1.5 tablespoons fresh lemon juice to brighten. Sea salt flakes and freshly ground black pepper to taste.

Instructions

Soak the cashews: Place 1/4 cup raw cashews in a heat-safe bowl and cover with boiling water. Let sit 30 minutes to soften. Drain, then add to a blender with 1/4 cup nutritional yeast and 2 cups unsweetened soy milk. Blend until perfectly smooth and set aside. If short on time, use hot water and a high-speed blender for a quicker puree. Cook the pasta: Bring a large pot of salted water to a rolling boil. Cook 12 oz lentil pasta according to package directions until al dente (usually slightly firmer than wheat pasta). Reserve 1/2 cup of the starchy pasta water before draining — it can loosen the sauce if needed. Sauté aromatics: Heat 1 teaspoon olive oil in a large saucepan over medium heat. Add 2 finely sliced yellow onions, cover and cook 5 minutes until softened and slightly translucent. Stir occasionally to prevent sticking and to encourage gentle caramelization. Build the vegetable base: Add 1 thinly sliced red bell pepper and 2 oz thinly sliced sun-dried tomatoes to the pan. Reduce heat to medium-low, cover, and cook 10 minutes, stirring regularly until bell pepper is tender and the flavors have concentrated. Season and thicken: Stir in 3 minced garlic cloves, 1.5 tablespoons tomato paste, 1.5 teaspoons cajun spices, 2 teaspoons smoked paprika, and a pinch of sea salt and black pepper. Cook 2 minutes, stirring constantly to toast the spices and cook off any raw tomato paste flavor. Then add 1.5 cups cooked butter beans and the reserved cashew cream; simmer 2 more minutes to let the sauce thicken. Assemble and finish: Add the drained pasta, 4 cups roughly chopped baby spinach, 1/4 cup chopped fresh parsley, and 1.5 tablespoons fresh lemon juice to the pot. Toss gently until the spinach is just wilted and everything is evenly coated. Adjust seasoning with salt and pepper and add a tablespoon of reserved pasta water if the sauce needs loosening.

Storage Tips

Cool leftovers quickly before storing: divide into shallow airtight containers to speed refrigeration and maintain texture. Stored in the fridge, portions last 3–4 days; freeze in single-serving vacuum or freezer-safe containers for up to 3 months. When reheating, thaw in the fridge overnight and reheat on the stovetop over low heat with a tablespoon of soy milk or reserved pasta water to revive the sauce. Avoid reheating multiple times — portion before storing to minimize repeated temperature changes. Look for visual cues of spoilage such as a sour smell, slimy texture, or dull color and discard if present.

Ingredient Substitutions

If you need to swap ingredients, sunflower seeds substituted 1:1 for cashews yield a nut-free cream with a slightly earthier flavor. For a lower-fat version, reduce cashews/sunflower seeds and increase soy milk to keep consistency, or blend in 1/2 cup silken tofu for added protein. If you don’t have lentil pasta, chickpea pasta is a similar high-protein alternative, though it will alter texture slightly. To reduce heat, cut the cajun seasoning in half and add a pinch of smoked paprika only. For a gluten-safe guarantee, ensure your lentil pasta is labeled gluten-free.

Serving Suggestions

Serve this pasta with a crisp green salad dressed in lemon vinaigrette to contrast the creaminess, or roast seasonal vegetables like Brussels sprouts or asparagus for a heartier plate. Garnish with extra parsley, a drizzle of high-quality olive oil, and toasted pine nuts or pumpkin seeds for crunch. For a Mediterranean twist, add a scattering of chopped olives or a spoonful of capers. This dish also pairs well with a chilled glass of dry white wine or a sparkling citrus soda for a refreshing counterpoint.

Cultural Background

While inspired by the viral “marry me” pasta concept — a creamy, tomato-forward sauce meant to impress — this version reflects both American meal-prep pragmatism and Italian-inspired flavors. The technique of building flavor through sautéing onions and caramelizing peppers before introducing concentrated tomato paste is rooted in classical European methods, but the legume-based pasta and cashew cream move it into modern plant-based innovation. It’s a fusion that honors comfort-food tradition while adapting to contemporary dietary preferences.

Seasonal Adaptations

In spring and summer, swap sun-dried tomatoes for fresh, roasted heirloom tomatoes and increase fresh basil with parsley for a garden-fresh finish. In autumn, add roasted butternut squash cubes and a pinch of cinnamon for warmth. During winter, use frozen spinach and ramp up smoked paprika and a bay leaf during simmering for deeper, cozier notes. The recipe scales well for holiday potlucks — keep the spice moderate for broad appeal.

Meal Prep Tips

Cook pasta just shy of al dente and cool quickly to stop cooking — this preserves texture after reheating. Pack with a small container of lemon wedges and a separate pouch of fresh parsley if you plan to freeze, adding them fresh at serving to preserve brightness. Label containers with the date and portion size; use clear, stackable containers for easy fridge organization. For grab-and-go lunches, include a small ice pack and reheat in the office microwave for 90–120 seconds, stirring halfway for even heat.

This recipe is a celebration of savory depth and plant-based nutrition. It’s the kind of dish that earns a permanent spot in the weekly rotation: versatile, forgiving, and reliably delicious. I hope you make it your own and find as much comfort in it as my family has. — Sarah Cobacho, plantbaes.com
