 Stuffed Onions – A unique and absolutely delicious side dish to elevate any meal!


  • 4 large sweet yellow onions
  • 1 cup broth (chicken broth or vegetable)
  • 6 slices of hickory smoked bacon, cut into 1 inch pieces
  • 2 slices of bread, cubed (I recommend sourdough)
  • 1/2 teaspoon ground black pepper
  • 3/4 tablespoon ground sage
  • 1 1/2 cups Gruyere cheese, shredded


  1. Preheat oven to 450 degrees F.
  2. Prepare onions by cutting off the top of the onion (approx. 1/3 inch). Remove tough outer layers. Cut off the bottom 1/4 inch just so they can sit flat. Use a spoon (or cookie dough scoop or melon baller) to scoop out the inside of the onion. 
  3. Save the excess onion flesh that you scooped out and roughly chop it; set aside to be used in the stuffing later.
  4. Place hollowed out onion shells in deep baking dish.
  5. Add chicken broth to the bottom of the pan.
  6. Bake for 20 minutes (middle rack + uncovered) and then remove onions from pan, drain liquid, and return them to the pan. Drop oven temperature to 375 degrees F. 
  7. While the onions are baking, cook bacon in a large skillet until it starts to get crispy. Scoop out excess grease so there is about 2-3 tablespoons left in the pan. 
  8. Add chopped onion and let cook down over medium heat for about 5-6 minutes, moving around fairly constantly.
  9. Add bread, sage and pepper; stir to combine.
  10. Remove from heat and fold in 1 cup of cheese.
  11. Stuff onions with bacon mixture and top with additional cheese.
  12. Cover loosely with aluminum foil and bake for approximately 15 minutes. Remove foil and let bake an additional 5 minute or until cheese is melted. 
  13. Let cool slightly, serve and enjoy!


  • Prep Ahead: you can easily prep the onions ahead of time by hollowing them out and leaving them in the fridge, covered.
