Uno's Rattlesnake Pasta Copycat

Total Time

We really enjoy Pizzeria Uno's Rattlesnake Pasta but eating out all the time gets expensive. I found this recipe online and we loved it. Next time I'll probably cut back to about 6 oz of the colby jack cheese, but it's definitely a keeper! (Edited the recipe to decrease the flour a little and the Italian seasoning after suggestions from raters)

Ingredients Nutrition


  1. The ingredients are in three groups. Above the penne pasta are the ingredients for the chicken. The penne pasta is in its own group. The ingredients below the penne are for the sauce.
  2. In a large skillet, melt 2 tablespoons of butter. Add minced garlic and Italian seasoning and cook for about 1 minute. Then add the chicken, cooking until done.
  3. Set chicken aside.
  4. Cook one pound of penne pasta according to instructions on package, removing from the water just shy of al dente.
  5. In the same pan the chicken was in, melt 4 tablespoons of butter. Add garlic and cook for about 30 seconds.
  6. Add the flour, salt & pepper all at once, to make a roux. Stir and cook for about 2 minutes.
  7. Add the milk and half-and-half to the roux, stirring constantly until smooth and thickened, about 5-6 minutes.
  8. Add the cheeses and stir until melted.
  9. Stir in chicken and jalapeno peppers.
  10. Toss with pasta.

I used to work at Unos, and this was one of my favorite dishes. But frankly you don't need to go through this much work to make it. Simply add green Tobasco to alfredo sauce and you are done--that's how they made it when I worked there, which was a ways back.

My whole family likes this pasta dish, and it's a great way to disguise the whole wheat pasta. It is on the rich and spicy side, so it is a once-in-a-while dish, but we love it when we have it.

My family loved it! It came out just perfect. Even better than the original dish from Uno's, in my opinion. I used whole wheat pasta and the rick creamy sauce disguised it well. The kids didn't even notice. Awesome!!!
