Heat 2 tablespoons of olive oil in a large skillet over medium heat. Sauté the onion until translucent, about 2-3 minutes.
Stir in paprika, 1.5 teaspoons salt, and pepper. Add garlic and tomatoes; cook for another 2-3 minutes.
Transfer tomato mixture to a blender. Blend with cottage cheese until smooth. Set aside.
In the skillet, heat remaining olive oil. Add tomato paste; cook for 1 minute. Add orzo; toast for 2 minutes.
Stir in zucchini, remaining salt, and chicken broth. Bring to a boil, then simmer with lid for 10-12 minutes until orzo is cooked.
Remove from heat. Stir in cottage cheese sauce. Let sit for 5 minutes.
Serve with fresh basil and red pepper flakes.
