Ingredients

  • 12 Ounces Pasta, shells or macaroni
  • 2 Tablespoons Olive oil
  • 1 Leek, chopped
  • 1 Pound(16oz) Baby bella mushrooms, chopped
  • 1 Tablespoon Lemon juice or white wine
  • 3 Tablespoons Vegan butter
  • 6 Cloves Garlic, chopped
  • 3 Tablespoons All purpose flour
  • 2 1/2 Cups Non-dairy milk, unsweetened I used oat milk
  • 1 1/2 Cups Vegan cheese, divided(I used mozzarella and parmesan)
  • Salt and pepper to taste

Topping

  • 1/2 Cup Panko bread crumbs, vegan
  • 1/4 Cup Vegan Parmesan
  • 2 teaspoons Olive oil

Instructions

  • Preheat the oven to 400 degrees(F).
  • Cook the pasta according to package directions, drain when al dente.
  • While the pasta cooks, heat the olive oil in a large pot on medium high.
  • Add the leeks and mushrooms. Sauté, reducing heat as needed, until the mushrooms have released their liquid and are starting to brown. This will take about 8 to 10 minutes. Season with a pinch of salt and pepper.
  • Then, remove the mushrooms and leeks from the pot, put in a bowl and set aside.
  • Now, pour the lemon juice or wine into the pot to deglaze the pot and scrap off any bits that are stuck to the bottom of the pot.
  • Add the vegan butter to the pot, and then once it has melted, add the garlic and sauté for 1 to 2 minutes.
  • Pour the flour into the pot and then whisk it into the vegan butter and garlic to make a roux.
  • Pour the non-dairy milk into the pot as well as a pinch of salt and pepper. Then whisk to fully combine. Making sure there are no lumps of roux left.
  • Bring to a simmer, then reduce heat to medium low and let simmer for 3 to 4 minutes or until the sauce is nice and thick.
  • Add 1 1/4 cups of vegan cheese(I used half mozzarella and half Parmesan), then whisk to combine, and continue to whisk until the cheese has melted into the sauce.
  • Taste and adjust seasonings, adding more salt, pepper or lemon juice if needed.
  • Now, add the leeks and mushrooms back into the pot, as well as the pasta once it is done. Toss to combine everything.
  • Pour the mac and cheese into a 9 x 9 inch baking dish and smooth out.
  • Top with the remaining 1/4 cup of vegan cheese.
  • Now, in a small mixing bowl, combine the topping ingredients, tossing it together so the panko is coated in olive oil.
  • Sprinkle the topping evenly on top of the mac and cheese.
  • Bake for 10 to 15 minutes or until the panko topping is golden brown. Serve!
