The sweet peppers, cheesy sauce, and tender chicken come together in the slow cooker like magic. And the best part? You just toss everything in and let it do the work. Whether it’s for dinner or your weekly meal prep, this dish is a total win!
Method in Detail
1. Prepping the Base
To start, I grab my slow cooker and add in the base ingredients that build all that fajita flavor. I place the chicken breasts directly into the pot, followed by sliced onion and crushed garlic cloves. Then I sprinkle in all the spices: cumin, oregano, chili powder, and smoky paprika. These spices give the dish that warm, slightly spicy flavor that tastes like a fajita in pasta form. Lastly, I pour in both cans of chopped tomatoes. I give everything a quick mix with a spoon to coat the chicken and let the flavors blend together. At this stage, I cover the slow cooker with the lid and cook everything for 3 hours on high or 6 hours on low, depending on my schedule.
2. Adding the Pasta and Veggies
After the base has cooked down and the chicken has started to soften, it’s time to add the second round of ingredients. I stir in the dry penne pasta and the sliced red pepper. Then I pour in 200ml of chicken stock to help the pasta cook. I always start with 200ml and keep an eye on it depending on your slow cooker, you might need to add more, but I never go over 300ml total. At this point, you can choose when to add the soured cream. Sometimes I mix it in now so it blends as everything simmers, or I wait and stir it through at the end to keep it fresh and creamy.
3. Final Slow Cook and Melting the Cheese
With everything in the pot, I close the lid again and let it cook for another 45 to 50 minutes. During this time, the pasta becomes tender and absorbs all those rich, tomato-spiced flavors. I always check around the 40-minute mark to make sure the pasta isn’t overcooking it should be soft but still holding its shape. Once the pasta is just right, I stir in the grated cheddar cheese and, if I waited earlier, the soured cream. The cheese melts into the sauce and makes it extra creamy and comforting. Give it a good mix to make sure everything is well combined.
4. Serving and Garnishing
Now it’s ready to serve! I ladle the chicken fajita pasta into bowls and top each one with a handful of freshly chopped coriander and a few slices of red chili for extra color and a little kick. This final touch not only looks great but also adds a pop of fresh flavor. And that’s it dinner is done!

2 cans chopped tomatoes
1 red pepper, sliced
3 tbsp soured cream
300g dry penne pasta
200ml to 300ml chicken stock
100g cheddar cheese, grated
Salt and pepper (to taste)
Fresh coriander and sliced chili (for garnish)
Directions
- Add the chicken breasts, sliced onion, crushed garlic, cumin, oregano, chili powder, paprika, and chopped tomatoes to your slow cooker. Let it cook for 3 hours on high or 6 hours on low.
- Next, toss in the dry pasta, sliced red pepper, and chicken stock. If you want, add the soured cream now or wait and mix it in at the end. Keep an eye on the liquid; if it looks dry, add a bit more stock. Don’t go over 300ml total.
- Let everything cook for another 45–50 minutes, or until the pasta is tender. Stir in the cheese and the soured cream now if you didn’t earlier.
- Serve hot and sprinkle with chopped coriander and a few slices of fresh chili. Yum!
Notes
- Don’t add too much stock at once start with 200ml and add more only if it looks too dry.
- If you leave the pasta in too long, it can get mushy, so check it around the 40-minute mark.
- If you use regular bell peppers instead of sweet ones, the flavor will be a bit stronger both work great, though!




Serving Suggestions
I love serving this with a fresh green salad or some warm garlic bread on the side. It also goes great with a spoon of guacamole or extra soured cream. If you’re packing it for lunch, it tastes even better the next day!
