Let’s cook!
Ingredients You’ll Need
This slow cooker Alfredo keeps things simple and flavorful.
- Chicken Breasts – sliced so they cook evenly in the creamy sauce.
- Heavy Whipping Cream – the rich base of the Alfredo sauce.
- Chicken Broth – low-sodium broth lightens the sauce.
- Butter – adds richness.
- Cajun Seasoning – gives the Alfredo a warm, savory kick.
- Fresh Garlic and Garlic Powder – double the garlicky flavor.
- Parmesan Cheese – freshly shredded, it melts into a smooth, cheesy sauce.
- Broccoli – tender florets that soak up the sauce.
- Salt, Pepper, Chili Flakes, and Parsley – to season and garnish.
Step-by-Step Instructions
First, make the sauce. In a large bowl, whisk together the heavy cream, chicken broth, garlic powder, Parmesan, salt, black pepper, and Cajun seasoning.
Next, fill the slow cooker. Place the sliced chicken, diced butter, minced garlic, and broccoli in the slow cooker. Pour the cream mixture over the top and stir gently.
Now let it cook. Cook on low for 4 hours or high for 2-3 hours, until the chicken reaches 165°F (74°C).
Finally, serve. Adjust seasoning if needed, then garnish with red chili flakes and fresh parsley.
That’s it! Creamy Alfredo with almost no effort.
Expert Tips
Use freshly shredded Parmesan. Pre-shredded cheese has anti-caking agents that can make the sauce grainy.
Taste your Cajun seasoning. Blends vary in salt and heat, so adjust to your taste.
Don’t overcook. Check the chicken at the earlier end of the time range so it stays juicy and the broccoli doesn’t get mushy.
Stir before serving. A quick stir brings the sauce back together if it separates slightly.
Recipe Variations
I love this recipe as it is, but it’s easy to change up.
For a milder Alfredo, swap the Cajun seasoning for Italian seasoning.
Add mushrooms, spinach, or sun-dried tomatoes for extra flavor.
Use chicken thighs instead of breasts for extra-juicy chicken.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for 3 to 4 days.
Reheat gently on the stovetop over low heat with a splash of cream or broth. High heat can cause the sauce to separate.
Serving Suggestions
Keep it low-carb by serving over zucchini noodles or cauliflower rice.
Or serve it over fettuccine or penne with warm garlic bread and a crisp salad.
Recipe FAQs
1. Is this keto-friendly?
Yes, the chicken, broccoli, and Alfredo sauce are naturally low-carb.
2. Can I use frozen broccoli?
Yes, but add it during the last hour so it doesn’t get too soft.
3. Why is my sauce grainy?
Pre-shredded Parmesan can cause this. Use freshly shredded cheese for the smoothest sauce.
4. Can I add pasta?
Yes! Cook it separately and toss it with the sauce before serving.
5. Is it spicy?
It has a mild kick from the Cajun seasoning and chili flakes. Reduce them for a milder dish.
