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:

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.

    This was my all time favorite dish every time we went to the restaurant in downtown San Diego. I never ordered anything else! Now I live in western New York, and was browsing in a gourmet shop and saw myzithra cheese! Since I really love the mizithra pasta as much as I do, I thought I’d give it a try. I have a question for your visitors. Has anyone tried sauted garlic along with the butter? I am also going to make it with crispy fried bacon pieces. Garlic and bacon always seem to work for me in many of the pasta dishes I cook and I haven’t had any complaints!

        You can’t mess this dish up! This was also my favorite thing on the menu in San Diego 40 years ago! I was in The Fresh Market in Jupiter,Florida and saw Mizithra cheese for the first time in all those years and decided to buy it and see if I could find the recipe. Brought back memories!

    • Elizabeth

      Personally, I’m not a fan of garlic, but would never dream of complaining about bacon in any way, shape, or form! 😁

    This IS the best recipe for a delicious dish, The recipe doesn’t mention when to add the parsley. I know it is a condiment at the end of the dish before serving, others might not know when to add the parsley so maybe you could add that to the directions.

    I find this as I sit here eating what I prepared last night–it doesn’t warm up well?!?
    I just took my leftover and threw it in a couple of tablespoons of brown butter in a saucepan and stirred it up. Just as good as last night!!!

    I love this recipe so much. I am 12 years old and I’ve been trying to find a good recipe for my mom to save money. This is perfect!!! My mom loves it as well. It’s easy enough to make and find, browning the butter is even a simple process too!

    Is there something else I can use instead of the Mizithra cheese? I can’t find any in the stores.

    So happy to see this recipe, simple though it is! This was one of my favorite dishes when the gang used to congregate at the Factory in college. We’d order several different “sauces” and eat buffet-style, but there was always at least one plate of this dish on the table. Thanks!

  7. Ron

    When I was doing some work there the manager told me it was goat cheese as the second cheese. He wrote it down for me and I lost it darn it. I think it was equal parts of each cheese.

    Thank you so much for this!! I live in Texas and The Spaghetti Warehouse doesn’t have this. I used to live in Cali and would get it every time I went there! Thanks again!!
