No one can resist a creamy cheesy casserole! There’s an old school broccoli casserole recipe, one of my Ma’s favorites, that serves as inspiration for this modified Brussel sprout version. The base of this casserole is a combination of butter roasted onions, cream of mushroom soup, mayonnaise, and shredded cheddar cheese. The quartered sprouts are added to the creamy mix, covered, and cooked until fork-tender. Then, a hearty mix of crushed ritz crackers and even more cheddar cheese is added as a topping, and then roasted until crisp. This is one tasty side dish or, double this recipe and bring it as your potluck contribution.

  • ½ cup chopped yellow onion
  • 4 tbsp (1/2 stick) salted butter 
  • 1 (10.5 oz) can cream of mushroom soup 
  • 2 large eggs 
  • ½ cup mayonnaise 
  • 5 cups quartered Brussel sprouts 
  • 1 cup cheddar cheese, divided 
  • 1 ½ cup crushed Ritz crackers


1) Place ½ cup chopped onion and 4 tbsp butter in a Suvie pan. Place the pan in the bottom zone of your Suvie and roast at 400°F for 15 minutes. 

2) Meanwhile, place 1 can cream of mushroom soup, 2 eggs, ½ cup mayonnaise, and ¼ teaspoon black pepper in a large bowl, and whisk until blended. 

3) Once the onions have roasted, add them to the bowl along with any residual butter. Add 5 cups quartered Brussel sprouts and ½ cup of cheddar cheese to the bowl, and toss to combine. 

4) Transfer the casserole mix to a Suvie pan (you can use the same pan used to roast the onions). (For Suvie 2.0 we recommend covering the pan with foil). Place the pan in the bottom zone of your Suvie, input settings, and cook now.
