Heat the olive oil and and butter over medium-high heat. When sizzling, stir in the orzo.
Saute and cook the orzo until about 25% of the pieces are golden brown.
Add the garlic and saute for 30 seconds.
Add the chicken broth, salt, and pepper. Bring to a boil. Lower the heat, cover, and let simmer for 10 minutes.
Remove the lid, stir, and cover and simmer another 3-5minutes, until done and most of the liquid is absorbed.
Before serving, add the lemon zest and juice. Taste for salt and pepper, adjust, and serve.
