Understanding Turkey a la King
Turkey a la King is a classic American comfort dish known for its rich and creamy sauce, typically featuring cooked poultry, mushrooms, and various vegetables. The “a la King” designation generally refers to a dish served in a rich cream sauce, often with sherry, and frequently presented over toast points, rice, or biscuits. Our slow cooker version takes this beloved classic and simplifies the process, allowing the flavors to meld beautifully over hours of gentle cooking. It retains all the traditional charm and comforting qualities while making it incredibly accessible for busy households and perfect for making the most of leftover holiday turkey.
Key Ingredients for Success
Every ingredient in this Slow Cooker Turkey a la King plays a crucial role in building its incredible flavor and texture. Here’s a closer look at what you’ll need:
- Leftover Cooked Turkey: The star of the show! Hearty and flavorful, the cooked turkey is the foundation of this dish, providing tender chunks of protein.
- Onion: Adds a fundamental savory, aromatic base that deepens the overall flavor profile. Diced small, it melts into the sauce.
- Green Pepper: Contributes a fresh, slightly bitter note and a vibrant color, offering a pleasant counterpoint to the rich sauce.
- Red Pepper: Brings a touch of sweetness and another pop of color, enhancing both the taste and visual appeal of the dish.
- Celery: Offers an earthy, subtly savory flavor and a delicate crunch, adding essential texture and aroma.
- Chicken Broth: Infuses the dish with moisture and a profound depth of savory flavor, forming the liquid base for our creamy sauce.
- Cream of Mushroom Soup: This classic pantry item acts as the primary thickener and flavor enhancer, creating a rich, deeply creamy, and savory foundation for the A la King sauce.
- Garlic Powder: A versatile seasoning that provides a warm, pungent flavor boost, complementing the savory notes of the turkey and vegetables.
- Salted Butter: Essential for richness and flavor, butter also aids in gently cooking and softening the initial vegetable blend, creating a smooth base.
- Frozen Peas: Added towards the end, these tiny green gems contribute a pop of vibrant color and a burst of natural sweetness, along with a tender texture.
- Sliced Mushrooms: Earthy and meaty, mushrooms add a satisfying umami depth and a chewy texture that pairs perfectly with the creamy sauce and turkey.
- Heavy Whipping Cream: The secret to an extra luxurious and silky-smooth sauce, heavy cream provides unparalleled richness and a decadent finish.
- Biscuits (for serving): Flaky, warm biscuits are the perfect vehicle for soaking up all the creamy, flavorful goodness of the Turkey a la King, making for an incredibly comforting bite.

Crafting Your Slow Cooker Turkey a la King
Making this Slow Cooker Turkey a la King is a breeze. Follow these simple steps for a truly delicious and satisfying meal:
- Step One: Combine Initial Ingredients
Carefully add the leftover cooked turkey, diced onion, green pepper, red pepper, celery, chicken broth, cream of mushroom soup, garlic powder, and salted butter directly into your slow cooker pot. Ensure all ingredients are well distributed within the pot. - Step Two: Slow Cook to Perfection
Secure the lid firmly on your slow cooker. Cook the mixture on the LOW setting for approximately 6 hours, or if you’re in a bit more of a hurry, you can cook it on HIGH for 4 hours. This slow cooking process allows all the savory flavors to meld beautifully and the vegetables to tenderize perfectly. - Step Three: Incorporate Final Touches
About 30 minutes before you plan to serve the meal, remove the lid and stir in the frozen peas, sliced mushrooms, and heavy whipping cream. Stir until everything is thoroughly combined. Allow it to cook for the remaining time, giving the peas and mushrooms time to heat through and the cream to integrate into the luscious sauce, thickening slightly. - Step Four: Serve and Enjoy
Once thoroughly heated and creamy, ladle generous portions of your delicious Slow Cooker Turkey a la King over warm, freshly baked biscuits or your preferred serving base. Serve immediately and savor this delightful, hearty meal.

Perfect Pairings for Turkey a la King
While biscuits are a classic accompaniment, Slow Cooker Turkey a la King is incredibly versatile and pairs wonderfully with a variety of side dishes. Here are some delicious ideas to complete your meal:
- Rice or Noodles: For a truly hearty and satisfying base, serve your creamy turkey mixture over a bed of fluffy white rice, brown rice, or your favorite pasta noodles, such as egg noodles or rotini.
- Mashed Potatoes: Soft, buttery, and incredibly comforting, mashed potatoes are an excellent choice. Their creamy texture perfectly complements the rich sauce of the A la King.
- Toast or Biscuits: Crisp, golden toast points or warm, flaky biscuits are traditional serving options, ideal for soaking up every last drop of the delectable sauce.
- Steamed Vegetables: To add freshness and balance, serve a side of simply steamed broccoli florets, vibrant green beans, or sweet corn. They offer a delightful textural contrast.
- Fresh Green Salad: A light and crisp green salad, dressed with a tangy vinaigrette, can cut through the richness of the dish and provide a refreshing element to your plate.
- Cornbread: A slightly sweet and crumbly cornbread offers a wonderful flavor pairing with the savory turkey and creamy sauce. Try serving it warm with a pat of butter.

Creative Variations and Smart Substitutions
One of the best aspects of Slow Cooker Turkey a la King is its adaptability. Feel free to get creative with these variations and substitutions to make it your own:
- Turkey Alternatives: If you don’t have leftover turkey on hand, cooked chicken works just as wonderfully. You can easily use shredded cooked chicken breast, leftover rotisserie chicken, or even sautéed chicken thighs for a delicious alternative.
- Expand Your Vegetable Choices: Enhance the nutritional value and flavor by incorporating other vegetables. Try adding fresh or frozen broccoli florets, sweet corn, diced carrots, or even spinach (stirred in at the very end). A bag of frozen mixed vegetables is also a convenient option.
- Experiment with Sauce Options: For a sophisticated and tangy twist, consider replacing half of the chicken broth with a dry white wine or a splash of dry sherry. For a lighter version of the sauce, you can substitute half-and-half or even evaporated milk for the heavy cream, while still maintaining creaminess.
- Spice It Up to Your Liking: If you enjoy a bit of heat, a pinch of cayenne pepper or a sprinkle of red pepper flakes can add a delightful kick. Fresh herbs like finely chopped thyme or rosemary, added with the peas and mushrooms, can also elevate the overall aroma and flavor. A touch of smoked paprika can add a subtle depth.
- Innovative Serving Ideas: Beyond biscuits, consider puff pastry shells for an elegant presentation, individual bread bowls for a rustic touch, or even serve it over polenta or pasta for a truly hearty meal. For those looking for a low-carb option, serve it over zucchini noodles, cauliflower rice, or steamed spaghetti squash.

Storage and Reheating Instructions
This Slow Cooker Turkey a la King is excellent for leftovers, making it perfect for meal prepping or enjoying throughout the week.
Refrigeration:
Allow the Turkey a la King to cool completely before transferring it to an airtight container. When properly stored in the refrigerator, it will remain fresh and delicious for approximately 3 to 4 days. This makes it a fantastic option for quick and easy lunches or dinners during the week.
Freezing:
For longer storage, freezing is an excellent choice. Transfer the cooled Turkey a la King into a freezer-safe container or heavy-duty freezer bags, ensuring you leave a little headspace for expansion. It can be safely frozen for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating Tips:
To reheat, you have a couple of convenient options. If using a microwave, place a single serving in a microwave-safe dish and cover it loosely to prevent splattering. Heat in 1-minute intervals, stirring in between, until thoroughly warmed through. Alternatively, for larger quantities or a stovetop preference, transfer the mixture to a saucepan or pot and heat over low to medium-low heat, stirring frequently, until it is hot throughout. If the sauce appears too thick after reheating, you can add a splash of chicken broth or milk to achieve your desired consistency.

Expert Recipe Tips and Tricks
Achieve the best possible results with your Slow Cooker Turkey a la King by keeping these helpful tips in mind:
- Maximize Leftovers: This recipe truly shines as a way to utilize leftover turkey from holiday feasts. If turkey isn’t available, cubed cooked chicken (rotisserie, baked, or pan-fried) is an excellent and equally delicious substitute.
- Create Lighter Options: For a dish with fewer calories and less fat, consider swapping out the heavy whipping cream for non-fat evaporated milk and using a low-fat or condensed cream of mushroom soup. These simple changes allow you to enjoy the rich flavors without the added richness.
- Effortlessly Thicken the Sauce: Should your sauce turn out thinner than desired, a quick fix is to create a cornstarch slurry. Whisk together 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth. Stir this mixture into the slow cooker during the last 30 minutes of cooking, after adding the peas, mushrooms, and cream. The sauce will visibly thicken as it cooks.
- Pre-Chop for Quick Prep: To make meal prep even faster, chop your onions, peppers, and celery ahead of time. You can store them in airtight containers in the refrigerator for up to 2-3 days, ready to be tossed into the slow cooker.
- Season to Taste: Always taste and adjust seasonings before serving. Depending on the saltiness of your chicken broth and cream of mushroom soup, you may need to add additional salt and freshly ground black pepper to perfect the flavor.
Alternative Stovetop Instructions
If you prefer a quicker cooking method or don’t have a slow cooker, this Turkey a la King can also be prepared on the stovetop. It’s perfect for a weeknight meal when time is of the essence.
- In a large skillet or Dutch oven, melt the butter over medium heat.
- Add the diced onion, green pepper, red pepper, and celery to the skillet. Sauté for 5-7 minutes, stirring occasionally, until the vegetables are softened and fragrant.
- Stir in the sliced mushrooms and cook for an additional 3-4 minutes, allowing them to soften and release their moisture.
- Pour in the chicken broth, cream of mushroom soup, and garlic powder. Stir well to combine all ingredients thoroughly.
- Add the cooked turkey to the mixture and bring it to a gentle simmer. Let it cook, stirring occasionally, for about 10-15 minutes, allowing the flavors to meld and the mixture to heat through.
- Finally, add the frozen peas and heavy whipping cream. Stir until well combined and continue to cook for another 5-10 minutes, or until everything is heated through and the sauce has thickened slightly to your desired consistency.
- Serve immediately over biscuits or your chosen accompaniment while hot.
