What makes the Spaghetti Factory Mizithra Cheese and Browned Butter so good?

Brown Butter Spaghetti is a traditional Italian recipe for brown butter pasta, but The Old Spaghetti Factory makes it its own with the addition of Mizithra cheese. This minor tweak makes a major difference in the dish’s taste without adding extra work.

If you love the nuttiness of browned butter, you are definitely going to want to try this new take on tradition. And if you are new to brown butter sauce, this recipe will open up a lot of new pasta-bilities. 

Why You Should Try This Recipe for Mizithra Cheese and Browned Butter

Few entrees can match the simplicity of ingredients with the intensity of flavor quite like The Old Spaghetti Factory’s Spaghetti Mizithra. But if you have tried making this dish using other copycat recipes online, you probably were more than a little disappointed.

After checking out a few of these online recipes, the reason is clear. Most recipes to recreate this Spaghetti Mizithra at home leave out the Romano cheese! Without the sharpness of Romano cheese, the dish tastes too earthy and dull. But all it takes is equal portions of Romano and Mizithra cheese to bring the pasta to life.

What is Mizithra Cheese?

There’s no shame in not knowing about Mizithra cheese; it’s pretty uncommon in the US. Mizithra is a unique Greek cheese incorporating the whey left behind from making sheep or goat milk cheese. So, what does Mizithra cheese taste like? Younger Mizithra cheese has a soft and creamy consistency similar to ricotta, but once aged, it becomes harder with a pronounced nutty flavor. Go with the aged version for this recipe.

If you are wondering where to buy Mizithra cheese, the truth is that it can be challenging to find. And if you do find it, it isn’t cheap. So, if you don’t want to spend the effort or money to get Mizithra, you can always substitute Parmesan cheese. The flavor won’t be precisely the same as what you get in the restaurant, but it will still be delicious.

The Old Spaghetti Factory Mizithra Cheese Pasta Ingredients 

For this pasta dish, you’ll need:

  • Pasta
  • Unsalted butter
  • Mizithra cheese
  • Romano cheese
  • Fresh Parsley

Ingredient Notes

The Old Spaghetti Factory uses spaghetti noodles in this dish, but you can use your favorite pasta type. 

Why not make things easier by buying The Old Spaghetti Factory Grated Mizithra & Romano Cheese Blend from the store? It can be found at some grocery stores. Or you can use grated Parmesan as a Mizithra cheese substitute.

How to Make Old Spaghetti Factory Mizithra Cheese Pasta

To prepare this dish:

  1. Bring a stockpot of well-salted water to boil and cook the pasta to al dente according to the instructions on the package. While the pasta is cooking, you can prepare the rest of the dish. 
  2. Grate the Mizithra and Romano cheeses. Set aside.
  3. Rinse, dry, and chop the leaves of the parsley. Keep it for later. 
  4. Brown the butter in a small saucepan. If you don’t know how to brown butter, check out the “A Bit About Browning Butter” section below.

  1. In a large mixing bowl, toss together the hot browned butter and pasta. 
  2. Add the grated Mizithra and Romano cheeses while tossing the pasta to coat the pasta evenly.
  3. Plate the sauced pasta and garnish with chopped parsley. Serve with extra grated cheese on the side.

A Bit About Browning Butter 

Browning butter doesn’t mean burning it. But don’t worry if you are not a master chef; as long as you pay attention, it’s not complicated:

  1. Heat a light-colored saucepan over medium heat. Using a light-colored saucepan makes it much easier to tell the color of the butter. 
  2. Cut the butter into even-sized pieces. Using pieces of butter that are all the same size ensures even melting and prevents burning. 
  3. Gently swirl the saucepan and stir with a silicone spatula. 
  4. While swirling the saucepan, let the butter come to a slow simmer. Adjust the heat as needed.
  5. Once the butter stops foaming and the butter turns a light tan, remove the saucepan from the heat.
  6. Continue to stir the butter in the saucepan off the heat. It will continue to darken and develop a nutty smell, but you are less likely to burn the butter. 
  7. Pour the browned butter into a bowl. Don’t leave behind the brown bits since they have the most intense flavor.

What to Serve With This Spaghetti Factory Mizithra Cheese Recipe

At the restaurant, you can get bread or salad, but at home, you have many more choices. Here are just a few:

  • Sauteed broccoli rabe. The bitterness of the broccoli robe pairs incredibly well with this pasta dish’s nutty, earthy flavor. 
  • Garlic bread. Everyone loves this classic side, and it’s so easy to make. 
  • Chicken breast. A simply seasoned grilled chicken breast is perfect paired with this pasta. 

How to Store the Leftovers 

It is best to cook only as much as you’re ready to enjoy immediately since this dish doesn’t keep very well. But the good news is that it only takes a few minutes to make the sauce, and you can store cooked and cooled pasta in an airtight container in the fridge for a couple of days.

    I’m late to the party but cotija cheese works really well in this recipe. Not spaghetti factory taste but very good. It does have a distinct briny type taste. I think I’ll mix with parm tonight. Mizithra has been impossible to find in my neck of the woods since covid. I can’t go to any function without bringing your recipe for Jimmy Buffets mac and cheese. Trust the process and follow that one to the letter. Thank you!

    I’d never had Mizithra until tonight when I tried your recipe and it was wonderful. I would say that the pepper at the end took this dish over the top. Love, love, love it. Thank you for the recipe!

    I have always loved this spaghetti with Mizithra from These Restaurants, in different parts of the Country! The Best was in Salt lake City in the 80’s and served generously, as in Hawaii, but some other places, like in Duarte and Stockton, CA. were a bit skimpy on the amount of pasta?
    The other attempts at preparing it at home was to brown the butter with about 1 tsp. of grated fresh Garlic into the bubbling mixture! The results were quite close to the restaurants! but I actually do not know if they even use garlic! It was pretty darn Close! Also, the browned butter particles are absolutely needed in the spaghetti! It’s the nutty flavo, that makes it so delicious!!

    Made this tonight and good grief, that’s a LOT of butter, even when you spoon off the top layer. I recommend draining the butter immediately after tossing with noodles. Used the OSF cheese blend, but it’s not even close to getting it in the restaurant. Someone here said OSF uses angel hair pasta, but that’s not true here in the Pacific NW. If I ever make this again I’ll use half the butter and try thin spaghetti.

    Old Spaghetti Factory uses angel hair pasta, as with any recipe, choose your own noodle to use. Have made this a few times, it is excellent.

    Although I lived in Toronto for many years, I never ate at the Old Superhero Factory. Sound like a delicious meal. That, however, is NOT spaghetti in your video.

      I wish I could share a pic. This was so yummy. I actually found SF’s mixed cheese at Fry’s. I also roasted up mushrooms, tomatoes, broccoli, and cauliflower. Added some chopped green onions and parsley. Side of country sourdough to dip in olive oil and seasoning. Boy oh boy!! Nom! Nom! Nom!

    I miss eating at the Old Spaghetti Factory. We grew up eating there. I’ve got a couple of pounds of Mizzithra cheese always. Thank God some of stores out here now carry it. Personally, I like that pasta dish without Romano cheese. My Dad would always order for me without it. Also, I don’t mind reheating it. It’s still really good. It’s even good as a cold spaghetti salad. Just add fruit, grapes, strawberries, etc. and a variety of nuts. Many times, I ate it cold. Thank you so very much for sharing this recipe. I’m looking forward to making it soon. And of course I’ll go ahead and add the Romano. As I get older, I’ve realize I enjoy a wide variety of different cheeses. Thank God for this too. Giving me a husband that can cook and not be stuck in a rut cooking the same thing everyday. I’m glad my daughter told me about you. Thank you for taking the time to share your knowledge and recipes. God Bless🥰🥰🥰

        all you have to do to reheat is bring the leftovers to room temp then add a splash or two of chicken stock and reheat mixing every few seconds in the microwave not as good as fresh but certain yummy
