You'll love this fresh take on spaghetti bolognese. It's filled with a hearty mixture of mushrooms, lentils, walnuts, and aromatic veggies.

Have you seen those lists of the new 2017 trends? You know, the ones that go around the internet this time of year predicting everything from the popularity of coconut oil to the color of pale pink we’ll all be wearing in the spring? One that’s caught my attention lately is that “they” are saying that staying in is the new going out. And I’m totally on board with that. If you’ve had a busy holiday season how good does this sound: Stretchy pants, spaghetti bolognese, wine, and a nice dinner by the fire with twinkly Christmas tree lights in the background?
Ok, just kidding. We don’t have a fireplace, and we haven’t even put up the Christmas tree, because if you remember last year it was FEBRUARY before we got around to taking the thing down. But festivity aside, let’s make pasta, shall we?

What is spaghetti bolognese?
I’m calling this a spaghetti bolognese, although I realize that Italian grandmothers are shaking their heads right about now. In traditional spaghetti bolognese, pasta is topped with a tomato sauce made of aromatic vegetables, red wine, and a mix of beef and pork. While this bolognese sauce is not exactly authentic, it’s equally delicious, made with a hearty mix of mushrooms and lentils that get all stewy with onions, carrots, tomatoes, and rosemary, among other savory ingredients.

My Twist on Spaghetti Bolognese
Hidden in this spaghetti bolognese recipe are some unconventional ingredients. I find that balsamic vinegar and soy sauce bring out a rich flavor in the mushrooms. Sage (to me) has a sausage-like scent, so I used a bit of dried sage to bring a depth of flavor to the sauce. In addition to the lentils, I added some finely crushed walnuts that you won’t detect, but they add some richness to this no-meat situation.
I used canned tomatoes as the base of the sauce and tossed in some sliced fresh tomatoes near the end for no other reason except that I find brown foods exceptionally challenging to photograph 🙂

Aside from that whole not having a Christmas tree thing – Christmas came early because I got the chance to cook with KitchenAid’s new Stainless Steel Cookware set. The polished stainless steel is so fancy! The 12-inch skillet cooked my stewy sauce perfectly, and these pieces were a breeze to clean. Plus, how pretty is this large pot (and Jack’s action-pasta drop shot!):

What to Serve with Spaghetti Bolognese
Cook your pasta until al dente, toss it with the sauce, and serve! We like ours with steamed green veggies or another simple vegetable side. Roasted cauliflower, asparagus, green beans, and zucchini are some of our favorites.
It would also be good with a green salad and crusty bread. Make up your own, or try this arugula salad, this spring salad, this Brussels sprout salad, or this kale salad.

Try my lasagna, pasta pomodoro, roasted vegetable pasta, or penne pasta next!

Spaghetti Bolognese
Ingredients
- 2 tablespoons extra-virgin olive oil
- ½ yellow onion, diced, about 1 cup
- 1 medium carrot, diced
- 4 cups chopped cremini mushrooms
- 1 tablespoon chopped rosemary
- ½ cup walnuts, crushed
- 2 garlic cloves, minced
- 1 tablespoon balsamic vinegar
- 1 tablespoon tamari
- 1 14-ounce can fire roasted diced tomatoes
- 1 1/2 cups cooked brown or green lentils*
- 1 tablespoon tomato paste
- 1 teaspoon dried sage
- 1 cup halved cherry tomatoes
- 8 ounces spaghetti
- 1 cup sliced fresh basil, optional
- ½ cup toasted pine nuts
- red pepper flakes
- shaved pecorino cheese, skip if vegan
- Sea salt and freshly ground black pepper
Instructions
- Heat the oil in a large skillet over medium heat. Add the onion and carrot and pinches of salt and pepper and cook until they begin to soften, about 3 minutes. Add the mushrooms, another pinch of salt, and cook until soft, stirring only occasionally, about 8 more minutes.
- Stir in the rosemary. Push everything to one side of the pan to make room for the walnuts. Add the crushed walnuts and toast them for about 30 seconds, then stir everything together. Stir in the garlic, then add the balsamic vinegar and tamari and stir to incorporate. Add the tomatoes, lentils, tomato paste, sage and fresh cherry tomatoes, and stir.
- Reduce the heat and simmer for 20 to 30 minutes until the sauce thickens. Season to taste.
- Bring a large pot of salted water to a boil. Prepare the pasta according to the instructions on the package, cooking until al dente. Drain and add the pasta to the pan with the sauce.
- Serve with fresh basil, pine nuts, pinches of red pepper flakes and pecorino cheese, if desired.

Have you tried freezing the sauce? I’m a vegetarian and my husband is the exact opposite. I’m always trying to find recipes that I can package for one person. I love lentil-mushroom “meatballs,” but they take more planning.
Hi Kathy, you could totally freeze this sauce!
It is always nice to see creative versions of classic pasta dishes. Adding vegetables to spaghetti makes it more nutritious while still keeping the dish comforting and enjoyable.
Made this today just as the recipe explains, it is fantastic! I loved it – mmm….will make again. Thank you!
I’m allergic to mushrooms (so sad!). Any other substitutes or just prepare with same omitted
Hi Stephanie, I would increase the walnuts by 1/2 cup if you’re skipping the mushrooms. You could also add some chopped oil-packed sun-dried tomatoes to the sauce when you add the lentils to make up for the missing umami. Alternatively, you might like this pasta recipe, which is mushroom-free!
This is just flat out fantastic! I recommend overcooking the lentil a bit. It allows for them to partly dissolve as part of the sauce.
Hi Christina, great tip! So glad you love the recipe.
This dish checked all the boxes! It was delicious, healthy, and easy to make. The flavors and textures were really nice.
I followed the recipe precisely (except for using a whole onion and doubling the tomatoes). Topping it off with shreds of basil, grated parmesan, toasted pine nuts, and chili flakes added a nice touch.
I’m so glad you loved the recipe!
Can we get a nutritional profile?
Would be helpful to include the nutrition profile. Maybe it’s here but I missed it?
Since all the ingredients are dry. I added vegetable broth to make it more sauce like.
I used to love adding lentils to things like this, but my digestive system cannot handle it. Gives me awful, unmentionable issues. So is there a good alternative I can try?
wonderful final product! served with roasted zucchini spears. take note: the amount of cooked lentils required is much less than the amount of lentils to cook. Think about it. we have lentils leftover. Also, maybe its just me, but the amount of chopping and prep took me much longer than 20 min.! also, when i do it again, i would add more liquid to sauce it up. (more tamari or canned tomatoes) it was a bit thick. Used mac nuts to sprinkle at end and it was a crowd pleaser!
I found this recipe and was excited because I had all the ingredients on hand. But when it came time to add the lentils I realized they were supposed to be precooked! So I used a can of cannelloni beans which worked fine but honestly I think it would have been even better without them. The taste of the mushrooms, tomatoes, herbs etc. were really good.
Delicious! My family loved it too – it was very tasty.
Any idea what the nutrition breakdown is? My wife loved it but she is doing zoom and is trying to enter it in the program.
My family liked it but didn’t love it.
To me the balsamic vinegar over powered the dish. I would like to try it again without the balsamic vinegar.
I wanted to love this, but the flavor was not good. It *looked* nice and “meaty” but neither me or my family liked the flavor or the texture. Would never make again. Sorry.
I’m sorry you didn’t enjoy this one.
It’s good
Ok, this was amazing! My picky husband and daughter ate it up. The only thing I did different is added 2 tablespoons of the tomato paste, and increased the balsamic vinegar and tamari by 1 teaspoon each, and added 2/3 cup of water because it wasn’t saucy enough for me. Needless to say they asked for more!
Made this tonight and it turned out tasty! Only difference, I probably used about 1/2 cup of cooked lentils. I did not use tamari or any cheese. It was a very thick sauce, very hearty. Good for cold winter nights. And I have enough for leftovers tomorrow! Yum!
Yes! I loved the fact that there was leftovers for us. I think I will use the leftovers as a base for a chili or soup.
Oh good call!
This was delicious! Hearty, filling, and chock-full of goodness! I left out the rosemary and used gluten free spaghetti. Yum!!
We are not a vegan/vegetarian family, but are trying to expand our horizons. This recipe was AMAZING! The whole family loved it. We did omit the mushrooms. We are making it for dinner again this week.
