How to Make French Onion Orzo Bake

Follow these straightforward steps to create this delicious one-pot meal.

  1. Heat olive oil in a large oven-safe skillet over medium heat. Add the sliced onions, salt, and pepper, stirring occasionally. Cook for about 20 minutes until onions are deeply caramelized and golden brown.
  2. Add the minced garlic and thyme to the onions, cooking for another minute until fragrant.
  3. Sprinkle the flour over the onions and stir well to combine. Cook for 2 minutes to remove the raw flour taste, stirring constantly.
  4. Pour in the beef broth while stirring to avoid lumps. Bring the mixture to a simmer, then add the orzo pasta. Stir well to ensure the orzo is evenly distributed.
  5. Let the orzo cook in the simmering broth for 10-12 minutes, stirring occasionally to prevent sticking. The orzo should absorb most of the liquid but remain tender.
  6. Remove the skillet from heat and stir in the butter until melted and incorporated.
  7. Sprinkle the mozzarella and Parmesan cheese evenly over the top of the orzo and onions.
  8. Transfer the skillet to a preheated oven at 375°F and bake for 10-15 minutes, or until the cheese is melted, bubbly, and golden brown.
  9. Let the bake rest for 5 minutes before serving to allow it to set.

You’ll know it’s perfectly done when the cheese is golden and bubbling, and the orzo is tender but not mushy, with a rich onion flavor throughout.

Tips for the Best Results

Get the most from your French onion orzo bake with these helpful tips.

  • Take your time caramelizing the onions for the best depth of flavor—low and slow is key.
  • Use an oven-safe skillet or transfer to a baking dish before adding cheese.
  • Stir the orzo occasionally while simmering to prevent it from sticking to the pan.

Frequently Asked Questions

Can I use a different type of pasta instead of orzo?

Cook the onions slowly over medium-low heat with occasional stirring, allowing natural sugars to develop gradually for an ideal caramelized flavor.
