Heat olive oil in your large pot over medium heat until shimmering. Add sliced sausage and cook for 5-7 minutes, stirring occasionally. You want golden brown edges that will add rich flavor to the entire dish.
Stir in minced garlic and cook for just one minute until fragrant. Don't let it burn or it will taste bitter. The kitchen should smell amazing at this point, signaling you're on the right track.
Add broccoli florets to the pot and sauté for 2-3 minutes. This brief cooking time helps them soften slightly while maintaining that perfect crisp-tender texture. The bright green color should remain vibrant and appealing.
Pour in chicken broth, add orzo pasta, Italian seasoning, salt, and pepper. Stir everything together well to ensure even distribution. The broth will cook the pasta and create a flavorful base.
Bring mixture to a boil, then reduce heat and cover. Simmer for 10-12 minutes, stirring occasionally to prevent sticking. The orzo should absorb most liquid and become tender but not mushy.
Remove from heat and stir in Parmesan cheese until melted and creamy. The residual heat will melt the cheese perfectly. Garnish with fresh parsley before serving for a restaurant-quality presentation.
