Ingredients Overview
- 2 pounds beef stew meat: Opt for well-marbled beef stew meat for maximum tenderness. The long slow-cooking process breaks down the connective tissues, making the meat melt-in-your-mouth soft.
- 1 can cream of mushroom soup: This serves as the base for the creamy sauce. For a homemade touch, you can use a homemade mushroom soup if preferred.
- 1 cup beef broth: Adds depth to the dish and enhances the beef flavor.
- 1 onion, diced: The onion adds sweetness and helps to balance the richness of the dish.
- 3 cloves garlic, minced: Fresh garlic gives a robust flavor that complements the beef.
- 1 teaspoon dried thyme: This herb brings a subtle earthy flavor that pairs perfectly with mushrooms.
- 1 teaspoon dried parsley: Adds a hint of freshness to the casserole.
- Salt and pepper to taste: Don’t skip seasoning; it’s essential to bring all the flavors together.
- 8 ounces sliced mushrooms: Use a mix of mushrooms like cremini and white button for extra flavor.
- 1/2 cup sour cream: Stirred in at the end for a rich and creamy finish.
- 2 tablespoons cornstarch: Helps thicken the sauce to a silky consistency.
- Chopped fresh parsley for garnish: Brightens up the dish before serving.
Step-by-Step Cooking Instructions
1. Prepare the Ingredients
Begin by prepping all the ingredients: dice the onion, mince the garlic, and slice the mushrooms. This makes the cooking process much smoother and more enjoyable.
2. Assemble in the Slow Cooker
In your slow cooker, combine the beef stew meat, cream of mushroom soup, beef broth, diced onion, minced garlic, dried thyme, dried parsley, salt, and pepper. Give it a good stir to ensure the ingredients are evenly distributed.
3. Slow-Cook the Beef
Cover the slow cooker and set it on low for 6-8 hours or on high for 3-4 hours. The beef should be tender and cooked through. The longer cook time on low will yield the best results, as the meat becomes exceptionally tender.
4. Thicken the Sauce
In a small bowl, mix the sour cream and cornstarch together until smooth. Add this mixture to the slow cooker along with the sliced mushrooms. Stir well to combine.
5. Finish Cooking
Cover again and cook on high for an additional 30 minutes. The sauce should thicken up to a creamy consistency that coats the beef and mushrooms nicely.
6. Serve and Garnish
Serve the casserole over a bed of cooked noodles or fluffy rice. Garnish with freshly chopped parsley to add a pop of color and freshness.
Valuable Tips for a Seamless Cooking Experience
- Tip #1: Sear the Beef Before Slow Cooking
For an extra layer of flavor, sear the beef stew meat in a hot skillet with a bit of oil before adding it to the slow cooker. This step isn’t mandatory but will elevate the taste. - Tip #2: Use Low-Sodium Broth and Soup
Control the saltiness of the dish by using low-sodium beef broth and cream of mushroom soup. You can always adjust the seasoning later. - Tip #3: Fresh Herbs for Garnish
Adding freshly chopped herbs, such as thyme or parsley, just before serving will bring a vibrant freshness to the rich flavors. - Tip #4: Let the Casserole Rest Before Serving
Letting the casserole rest for about 10 minutes before serving allows the flavors to meld and the sauce to thicken further. - Tip #5: Pair It Right
This dish pairs wonderfully with mashed potatoes, polenta, or a crusty piece of bread in addition to rice or noodles.
Storage and Reheating Tips
- Storage
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze the casserole for up to 3 months. Make sure to cool it completely before freezing. - Reheating
When reheating, thaw frozen portions overnight in the fridge. Reheat on the stovetop over low heat, stirring occasionally, until heated through. Alternatively, microwave individual portions on medium power, stirring halfway through.
