Add a light coating of olive oil to a large skillet over medium-low to medium heat. Add shrimp and cook for 30-60 seconds per side, just until the shrimp is mostly cooked through.
1-2 tablespoons olive oil, 1 pound shrimp
Remove shrimp from pan and set aside.
Add a light coating of olive oil to the skillet and add sliced sausages. Cook over medium heat for 1-2 minutes per side just until the sausages begin to brown up or crisp a bit.
12 ounces Kielbasa sausage, sliced into 1 inch pieces
Remove sausage from pan and set aside.
Turn heat to low and add garlic. Cook for about 30 seconds until fragrant and then add tomato paste and crushed tomatoes. Stir until heated through.
½ teaspoon dried rosemary, ½ teaspoon dried parsley, ½ teaspoon dried oregano, ½ teaspoon dried thyme, ½ teaspoon dried basil, ½ teaspoon smoked paprika, ½ teaspoon salt, ½ teaspoon pepper
Stir in chicken broth and then add fettuccini. Try to submerge the pasta and move them around as much as possible so they don't stick together.
2½ cups chicken broth, 10 ounces fettuccini
Bring to a simmer and then place lid on pan making certain you stir every few minutes so the pasta is not stuck to the bottom of the pan and it doesn't stick together.
If the sauce becomes very thick while the pasta is cooking, add additional chicken broth.
Cook until the pasta is cooked to your liking. I like it al dente which means it just has a slight bite to it. The pasta will also continue cooking just slightly while adding the remaining ingredients.
Remove the lid and stir in heavy cream.
¾ cup heavy cream
As soon as the sauce begins to simmer and thicken, add the shrimp and sausage back into the pan. Stir gently so everything is covered with the sauce.
Cook until the shrimp and sausage are heated through.
Add additional salt and pepper if needed.
Serve hot with a bit of freshly chopped parsley for garnish.
1 teaspoon fresh parsley
Notes
Use a skillet that's large enough to hold everything. I used a 3.5-quart skillet and it had enough space to add all the ingredients and stir everything together.
Be careful that you don't overcook your shrimp. The color will begin to turn pink and the shrimp will begin to curl into a "C". It's better to slightly undercooked them rather than overcook them. They will continue to cook when added back into the sauce.
If your pan is very hot after cooking the sausage. Remove it from the heat for 1-2 minutes before adding the garlic.
Once you add your pasta, try to stir it or move it around in the sauce. It's difficult at the beginning because the pasta is firm. As it begins to soften, it's easier to stir it around.
You may need to add additional chicken broth halfway through cooking time. When your sauce is thick and you can draw a spoon through it and it holds its shape, you'll want to add more broth. This will vary depending on the type of pasta you use and the amount of heat from your stove.
The amount of time it takes to cook your pasta varies. All fettuccini vary in thickness and cook time. The best way to determine if your pasta is cooked is to taste a piece. Bite into it and determine if it's cooked to your liking. Just be careful not to overcook it or it can become a bit mushy.
After you've added the shrimp and sausage back into the pan, you can add a bit more cream or broth if your sauce is too thick.
