Irresistible Step-by-Step Directions
- Serve and Top Things Off
- Either toss your drained pasta into the sauce or spoon sauce over each bowl of noodles. Finish with chopped parsley or basil and, if you fancy it, a good dusting of nutritional yeast or vegan parmesan.
- Fix Up the Sauce
- Once you fish out the bay leaf, splash in balsamic vinegar for zing. Taste, then add salt and black pepper till it’s just how you like it. If it’s gotten thick, stir in a bit of pasta water until you’re happy.
- Get That Pasta Ready
- As the sauce bubbles, bring a large pot of salted water to a rolling boil. Cook the spaghetti till just chewy, not mushy. Before you drain it, snag a cup of the water in case the sauce needs loosening.
- Let It Simmer
- When everything’s mixed, drop the heat and slap a lid on the pot. Simmer for forty to fifty minutes, stirring every so often. The lentils should be soft with a little bite. If your sauce gets extra thick, add broth or water, a bit at a time, to loosen it up.
- Toss in Tomatoes Broth Lentils Bay
- Next, stir in those rinsed lentils so they soak up all the savory stuff. Pour in crushed tomatoes and broth, scraping every tasty bit off the bottom. Toss in the bay leaf so it can work its magic while everything cooks.
- Stir in Tomato Paste and Soy Sauce
- Now add the tomato paste. Stir and cook for a couple of minutes so it gets dark and rich. Pour in soy sauce or tamari to bring more flavor and make the sauce silky.
- Drop in Garlic and Spices
- Add all the minced garlic and keep it moving for about a minute until you catch that awesome smell. Drop in the dried basil, oregano, and a bit of red pepper if using. Stir non-stop for half a minute to unlock all the flavors.
- Start With the Veggie Base
- Drizzle olive oil into a big pot over medium. Once it’s shiny, toss in onion and cook gently, giving a stir here and there, for about seven minutes. The onion should go soft and smell sweet, not get brown. Add your chopped carrots and celery—let them cook and soften for around ten more minutes. This takes a bit but makes the best flavor base.

Don’t skip the bay leaf—it gives this sauce a quiet, deep flavor that ties everything together. My mom always swore by it, and it’s the old-school trick that makes this perfect for chilly nights when you need to feed a crew.
Smart Storage Ideas
Cool leftovers completely and pop them into sealed containers. It’ll keep for four days in the fridge. Freeze up to two months if needed. Thaw slowly in the fridge and reheat gently on the stove—just add a splash of broth or water if it’s looking thick.
Simple Ingredient Swaps
If you can’t track down brown lentils, use green. Skip red ones—they fall apart, but French lentils work great. Gluten free pasta or zucchini noodles are perfect for other diets. No balsamic? Red wine vinegar does the trick.

Fun Ways to Dish It Out
Add toasted garlic bread and a crisp salad to round out dinner. Kids go crazy for a sprinkle of vegan cheese or pine nuts. If you want to sneak in more veggies, add mushrooms or chopped peppers with your other veggies.

Every family puts their own stamp on a dish like this, and this version is a tasty way to honor that.
Frequently Asked Questions About Recipes
- → Can I use red lentils here?
Stick to brown or green lentils because red ones fall apart too quickly. You'll end up with mush and miss out on that chunky texture.
- → How do I get a thicker sauce?
Let the sauce cook with the lid off so some liquid evaporates, or just add a little less veggie broth in the beginning. The lentils will make it creamier as they soften, too.
- → Can I swap in gluten-free noodles?
Absolutely, grab your favorite gluten-free spaghetti and cook it as the box says. The sauce goes just as well with those.
- → What fresh herbs are best for topping?
Throw on some chopped basil or parsley at the end. They bring a fresh taste and look really nice, too.
- → Is it okay to prep this ahead?
You can totally make the sauce ahead and keep it in the fridge. For best noodles, make pasta fresh and combine right before eating so it's not soggy.
- → What's a dairy-free way to get cheesy flavor?
Add a sprinkle of nutritional yeast or vegan parm for cheesy vibes, no dairy needed.
