Vegetarian Stovetop Pesto Macaroni and Cheese

Stovetop Pesto Mac Recipe

Stovetop Pesto Mac with BroccoliThis delicious Vegetarian Stovetop Pesto Macaroni and Cheese recipe is originally made on the stove, but can easily be made into a baked casserole, too!

New Years Food Resolutions

January is a funny month. We’re all motivated to lose weight and get healthy and eat light foods. But the weather is gray and cold and makes us want casseroles, mac and cheese, and hot chocolate. I’ve posted some lighter recipes in the past two weeks, but now it’s time for Pesto Mac.

Cheesy, carb-y Pesto Mac.

Yes, the same Pesto Mac I put in my What I Ate This Week last month. Except it’s not the same, because that version was a disaster. I didn’t measure my ingredients when I was making the sauce and it turned out way way WAAAAY too thick. Oops! But now I’ve perfected the recipe. And between working on this Pesto Mac and another mac and cheese recipe for a project I’m doing, I’ve learned a lot about making macaroni and cheese.

Add veggies to make your mac & cheese go further.

Broccoli is probably the most obvious vegetable to add. (They even sell boxed mac and cheese with little bits of dehydrated broccoli!) I also really like adding mushrooms, greens (like kale or spinach), roasted jalapenos or poblanos, cauliflower… anything that goes with the cheese you’re using, really. I mentioned this trick in my Vegetable Baked Ziti recipe—when you add a lot of veggies, you can get more servings out of the recipe. Which, especially with a high calorie dish like mac & cheese, is a good thing!

You don’t need to start with a roux. Really.

I know, this is kind of an unpopular opinion. I’ve posted a roux-less mac and cheese recipe on my blog before and I regularly make cheese sauces without butter. Now, some people say when you skip the roux, your sauce ends up tasting like flour. My opinion is that if you use a good, quality cheese, that’s not true. I like leaving the butter out sometimes to save calories. (This Pesto Mac recipe does start with a roux, though.)

I won’t use pre-shredded cheese anymore.

I have done a lot of experimenting with mac and cheese in the past month, with both bagged pre-shredded cheese and cheese shredded the old-fashioned way—by hand, by me. I think the results are better with cheese I shred myself. Pre-shredded cheese has an anti-caking ingredient added to it, and I really think it makes the resulting sauce a little bit off. I’m still using the bagged parmesan shreds in my mac & cheese, but for the softer cheese, I’ve switched to using the blocks of cheese and shredding them myself.

Stovetop Pesto Mac with Broccoli

Mac and cheese is freezer-friendly (with a few tweaks).

Full disclosure: I have not frozen this Pesto Mac, so I can’t say for sure that this recipe is freezer-friendly, but I can’t see why it wouldn’t be. But in general, mac and cheese is a great dish for making in advance and freezing. Here’s how:

  • Cook your pasta about 1 minute less than al dente. So whatever the package instructions indicate for al dente, subtract a minute. The pasta will get softer upon reheating, so if you cook it for the full amount of time, you’ll end up with mushy mac and cheese.
  • Make the sauce thinner. The first few times I froze mac and cheese, I was disappointed in the consistency of the sauce—it wasn’t smooth or creamy. The solution is to make a thin cheese sauce. After adding the milk, as soon as the sauce is smooth and coats the back of a wooden spoon, remove it from the heat and whisk in the cheese.
  • Transfer the mac and cheese to a casserole dish (make sure it’s one that can go freezer-to-oven!), top with breadcrumbs and additional cheese, and cover with plastic wrap. The plastic wrap should be pressed right up against the mac and cheese to prevent ice crystals from forming. Cover with casserole lid and freeze for up to 3 months. (Remember, don’t put hot food in the freezer—it should be chilled first!)
  • To reheat, remove from freezer, take off plastic wrap, and cover with foil. Bake at 350°F for 45–60 minutes; remove foil and bake 15–20 minutes more or until heated through. You can broil for about 5 minutes to brown the breadcrumbs on top.

It’s easy to fake baked mac and cheese.

Toast some panko in a small skillet and sprinkle it on your stovetop mac and cheese. Or top your mac and cheese with some additional shredded cheese, then sprinkle on the toasted panko. That way you get the creamy goodness (and immediate gratification!) of stovetop mac and cheese with the yummy crispy topping of baked mac and cheese. Win-win, right?

So tell me, how do you like your mac and cheese?

Stovetop Pesto Mac Recipe

Vegetarian Stovetop Pesto Macaroni and Cheese

Stovetop macaroni and cheese made with fresh broccoli and a creamy pesto cheese sauce.
Prep Time: 15 minutes
Cook Time: 15 minutes
Total Time: 30 minutes
Servings: 4 servings


  • 8 oz elbow macaroni
  • 1 large broccoli crown broken into florets
  • 2 cups reduced fat milk warmed
  • 1/4 cup unsalted butter
  • 1/4 cup all-purpose flour
  • 1 1/2 cups fontina cheese shredded
  • 1/2 cups parmesan cheese shredded, divided
  • 1/4 cup pesto
  • salt + pepper to taste

Toasted Panko Topping (Optional)

  • 1 tsp olive oil
  • 1/4 cup panko toasted


  • Bring a large pot of salted water to a boil. Cook macaroni according to package directions until al dente. Two minutes before cook time ends, add broccoli. When macaroni is done, drain immediately and set aside.
  • Melt butter in a large saucepan over medium heat. Add in flour and whisk into butter; continue to heat until mixture is golden brown, 3–5 minutes.
  • Slowly add milk to flour mixture, whisking constantly. Once sauce is smooth, cook until slightly thickened (about 3 minutes), continuing to whisk constantly.
  • Remove sauce from heat. Whisk in fontina and parmesan cheese, pesto, and salt and pepper. Fold in elbow macaroni and broccoli. Divide into bowls and top with toasted panko, if desired.

Toasted Panko Topping

  • Heat olive oil in small skillet over medium heat. Add panko and cook until golden brown, 3–5 minutes.


To make this Pesto Mac into a casserole, after pasta and broccoli have been incorporated into the cheese sauce, transfer Pesto Mac to small (about 9 x 9) casserole dish. Top with panko and additional shredded cheese; bake at 350°F for about 20 minutes. If top is not browned, broil for about 5 more minutes.

    Awesome! Excellent recipe and info! I agree with you – pre shredded cheese never melts well for mac and cheese. One of my fav things to add is dill-havarti cheese to my mac n cheese. Extra yummy!

      I don’t think I’ve ever put havarti in mac & cheese. I should try that!

    This is so great – both the recipe and the tips. I tried mac & cheese without the roux a couple of times, but the sauce was made with fontina cheese and heavy cream – so rich – and I felt like such a pig eating it! Delicious though. 😉

      When I’ve skipped the roux, I usually go the milk + cheese + a little flour route. I can see how cheese and heavy cream would be super heavy! 🙂

    oh mac & cheese… a weakness. My daughter and I both love it. I make it homemade at least a couple times a month for her. I love throwing in things like broccoli, green onions, bacon, mushrooms & chicken breast.

    I once measured out and priced the ingredients for making real mac & cheese vs. Kraft and found that I could use Tillamook Black Label Cheddar for the homemade version and it would still be slightly cheaper!

    It seems like mac and cheese is one of the most popular dishes on food blogs, and yet I’m one of the few who doesn’t really care for it. You’ve almost got me convinced with this pesto version though! I think if I did make it, I would want to add lots of greens like broccoli or kale as you suggested, and the pesto would help make it so that it doesnt just taste like I’m eating a bowl of creamy cheese (which I know for some people wouldn’t be such a bad thing!)

      My husband was never a fan of mac & cheese either–the cheese sauce is a little too much for him. But he likes it now because I usually make it with a lot of stuff thrown in. So maybe you’d like it that way too! 🙂

    Yum! This is an awesome post! I’m always using mac and cheese to squeeze some extra veggies into my kids. I personally think broccoli goes down much easier with mac and cheese, and that’s coming from someone who loves broccoli 😀 I love the pesto in this, I can’t believe I’ve never done that before, it sounds amazing. Oh, and I love your tip for faking baked mac. Totally doing that!

    We loved this recipe! My husband won’t stop raving about it. I did a few changes. I carmalized onion in butter then made my roux with that. Did everything according to the recipe, then topped with crushed town home crackers and halved cherry tomatoes, then baked. The tomatoes are a must! They get sweet and juicy in the oven.

    Love your recipes, Kiersten. I make mac and cheese using fat free natural yogurt instead of bechamel sauce. It’s not quite the same but it scratches my mac and cheese itch with a fraction of the calories! Love the idea above about putting sprouts in- I will definitely be doing that next time, maybe with some rosemary?

    This recipe was great. I used almond milk instead of reduced fat milk and it was delicious. I also added mushrooms and my kids loved it. I did cook the veggies in olive oil before adding them to the mac n cheese. This recipe is definitely a keeper.

    Living in England we get cookery shows later then the states. Watching The Kitchen I saw mac n cheese made with 2 cans of mushroom soup. Have you ever done this? Being disabled standing there making a roux is painful. I add salutes onions and mushrooms. Yum.
