Instructions
- Melt the butter in a medium pan over medium heat.
- Add garlic and stir until fragrant (about 30 seconds).
- Add cream, cream cheese, and parmesan. Stir until melted and creamy.
- Season with Cajun seasoning blend, salt, pepper, and a pinch of nutmeg.
- Simmer gently for 2–3 minutes until thickened.
Note: This creamy sauce is best finished together with your meal, not cooked separately. If you’re making Cajun chicken Alfredo or Cajun shrimp Alfredo, add this sauce at the end so it warms through without overcooking. If you’re pairing it with low-carb pasta, warm the sauce gently on its own just before serving.
Expert Tips
- Don’t pre-cook the sauce on its own. It’s meant to be stirred into hot chicken, shrimp, or pasta at the end. This keeps it creamy and stops it from splitting or thickening too much.
- Use freshly grated Parmesan cheese for the smoothest texture.
- Too thick? Add a splash of cream or broth to loosen it up.
- Too spicy? Stir in a bit more cream cheese to mellow the heat.
- For a punch of freshness, top with chopped fresh parsley or a squeeze of lemon.
Ingredient Swaps
- Swap cream cheese with mascarpone or cottage cheese.
- Use dairy-free cream and cheese for a vegan version.
- Try Creole seasoning if Cajun is too spicy.
Storage Tips
- Fridge: Store in an airtight container for 3–4 days.
- Freezer: Freeze in small portions for up to 2 months.
- Reheat gently on the stove or microwave with a bit of cream.
