roasted brussel sprouts and caramelized onions combine with four different kinds of cheese to bring a burst of flavor to this easy, wholesome pasta bake!


  • 1 lb whole wheat pasta (such as penne)
  • 16 oz whole fresh brussel sprouts (about 1.5 cups)
  • 1 medium onion (or 2 small), diced
  • 2 cloves garlic, peeled & minced
  • 2/3 cup whole milk ricotta cheese
  • 2/3 cup finely shredded mozzarella cheese
  • 2/3 cup finely shredded fontina cheese
  • 1/3 cup finely shredded parmesan cheese
  • Olive oil
  • Salt & pepper to taste


  1. Preheat oven to 425 degrees F and grease a large casserole dish.
  2. Halve brussel sprouts then toss with minced garlic, salt, pepper and a hefty drizzle of olive oil then place on a baking sheet and put in the oven for 20-25 minutes or until lightly browned and tender.  Keep oven on once removing brussel sprouts as you’ll use it in the last step.
  3. While brussel sprouts roast, cook pasta according to package instructions.
  4. Once pasta is cooking, place a non-stick sauté pan over medium heat and add another hefty drizzle of olive oil.  Add onions and sauté until they are a nice golden brown color (about 10 minutes).  Once cooked to golden brown, remove from heat & set aside.
  5. Mix together shredded mozzarella, fontina & parmesan cheeses and set aside.
  6. Drain pasta, place back into the pot and drizzle with olive oil.  Add in roasted brussel sprouts and caramelized onions.  Fold in ricotta with a rubber spatula making sure everything is coated with the ricotta.  Add most of the cheese mixture (reserving a handful or two for the topping) and toss to combine.
  7. Pour entire mixture into the prepared casserole dish, top with remaining cheese and pop back into the oven until cheese melts (about 5-10 minutes depending on your oven). 


Note: If saving some for leftovers, drizzle with olive oil after reheating as pasta can dry out a bit.
