Servings 8 servings


  • 1 (16 oz [453 g]) package penne pasta
  • 1 small head broccoli (optional)
  • 1 tbsp (15 ml) olive oil
  • 1/4 cup (56 g) vegan butter
  • 6 cloves garlic or 2 tbsp (18 g) jarred minced garlic
  • 1/4 cup (31 g) all-purpose flour
  • 1/3 cup (20 g) nutritional yeast
  • 3 cups (720 ml) plain unsweetened rice milk
  • 1 tsp dried parsley
  • 1 tsp dried basil
  • 1/2 tsp dried oregano
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 2 cups (226 g) vegan mozzarella cheese shreds divided
  • Salt and pepper to taste
  • Fresh or dried parsley for topping


  • Preheat the oven to 350°F and grease a 9″x13″ baking dish.
  • Cook the pasta to al dente according to the package instructions. If using the broccoli, add to the boiling water about 3-5 minutes before the noodles are done. Once cooked, drain and rinse in cold water, place back in the pot and toss with the olive oil to keep from sticking.
  • In a large skillet, melt the butter over medium-low heat. Stir in the garlic and let it cook for 30 seconds to 1 minute, or until fragrant. Whisk in the flour until thoroughly combined. Slowly pour in the rice milk, whisking constantly.
  • Increase the heat to high, bringing the mixture to a boil, whisking constantly. Lower the heat to low, bringing to a simmer. Stir in the nutritional yeast, parsley, basil, oregano, garlic powder and onion powder.
  • Allow to simmer for a few minutes, until it thickens. Stir in 1 cup (113 g) of mozzarella until melted. Stir in the cooked noodles and broccoli (if using). Taste and add salt and pepper as desired.
  • Pour into the prepared dish and top with the remaining 1 cup (113 g) of mozzarella.
  • Bake for 20-25 minutes, until the cheese is melted. Serve topped with parsley.
