Great way to use up Sourdough Discard
Sourdough discard is a great thickener for recipes like soups and this Sourdough Mac and Cheese recipe.
Ingredients
Sourdough Mac & Cheese
Uncooked Pasta – I used the classic elbow pasta, but be free to select your favorite type of noodle. Boil them for 1 minute less than the al dente time given in the box directions.
Butter – Unsalted or Salted butter works the same for this recipe.
Flour – All-purpose flour is added to make a roux for an extra creamy cheese sauce.
Unfed Sourdough Starter – Sourdough discard is a great thicker! Mix it in the milk till smooth for an extra creamy cheese sauce.
Dairy – I used a combination of milk and half and half for this cream sauce, but you could also do 1 cup of heavy cream and 5 cups of milk.
Shredded Cheese – I used a combination of cheddar and gruyere cheese, but you can experiment with other melty cheeses like fontina, mozzarella cheese, or Monterey jack.
Salt & Black Pepper – Season to taste
Sourdough Breadcrumb Topping:
Sourdough Breadcrumbs – Find instructions below on how to make your own sourdough breadcrumbs!
Butter – Helps the sourdough bread crumbs crisp up during the bake.
Parmesan Cheese – Who doesn’t love a little extra bit of cheese on top of their sourdough mac and cheese?
Paprika – Or swap with garlic powder or mustard powder. If you like some heat, sprinkle in a dash of cayenne pepper instead!
Supplies
Heavy Large Pot
Whisk

How to Make Sourdough Breadcrumbs
Preheat oven to 300 degrees F.
Add cubed pieces of sourdough bread, fresh or stale, into a food processor. Process on high for 30 seconds for coarse sourdough breadcrumbs or for 1-2 minutes for fine sourdough breadcrumbs.
Spread the breadcrumbs on a large rimmed baking sheet in an even layer and place into the preheated oven.
Bake for 5 minutes, stir, and then bake for an additional 10 minutes. The breadcrumbs should turn to a golden brown color and be dry to the touch.
Continue to bake for a few extra minutes, if necessary.
Remove the sourdough breadcrumbs from the oven and cool on a wire rack for at least 15 minutes.
Return the crunchy sourdough breadcrumbs to the food processor and process again if you desire more fine breadcrumbs.
How to Make Sourdough Mac and Cheese
Preheat the oven to 350 degrees F and grease a 3 qt. baking dish.
Combine the two shredded cheeses in a bowl and set to the side.
Bring a large pot of salted water to boil. Cook the pasta 1 minute shy of al dente according to the package instructions. Drain and drizzle with a touch of olive oil to prevent the noodles from sticking. Place in a bowl and set aside.
In a liquid measuring cup, whisk together the milk and sourdough discard until smooth.
Heat a heavy large pot, Dutch Oven, or large saucepan to medium-high heat. Melt the butter and then sprinkle in the flour. Whisk until dissolved and continue to cook for 1 minute.
Slowly pour in about half of the half and half into the flour mixture, whisking constantly until smooth. Continue to slowly add in the remainder of the half and half and milk/discard mixture. Continue to whisk and cook until the mixture begins to bubble and it coats the back of a spoon. Whisk in the salt and pepper.
Remove the pot from the heat. Sprinkle 2 cups of the shredded cheese into the smooth sauce. Whisk until smooth before adding another 3 cups. Stir until completely melted and smooth.
In a large bowl, combine the cheese sauce and the cooked pasta. Mix until thoroughly combined. Layer half of the pasta mixture into the prepared baking dish, top with the final cup of grated cheese, then pour the remainder of the homemade mac and cheese.
In a small bowl, combine the sourdough breadcrumbs, melted butter, parmesan cheese, and paprika. Mix with a spoon and then sprinkle the crunchy sourdough bread crumbs on top of the creamy mac and cheese mixture.
Bake in the oven for 30 minutes or until bubbly and golden brown. Serve hot and enjoy!
Tips:
Opt for freshly grated cheese over pre-shredded cheese for the smoothest, creamy cheese sauce.
Cook the pasta 1 minute shy of al dente. Since this is a baked Sourdough Mac and Cheese recipe, the pasta will continue to cook.
How to Store
Store leftover Sourdough Mac and Cheese in an airtight container in the fridge for up to 4 days.
To reheat, pour in a little extra cream or milk and heat until warm in the microwave. Stir often.
FAQs:
What kind of shredded cheese should I use?
I love the combination of shredded cheddar cheese and shredded gruyere cheese. The nuttiness and melty qualities of both cheeses are dynamite. But they can easily be swapped for cheeses like fontina, mozzarella, or Monterey Jack cheese.
Do you have to use sourdough breadcrumbs for the topping?
If you are low on time, you can substitute panko bread crumbs 1:1.
Happy baking!
