Can You Vary The Recipe With Other Ingredients?

  • Paleo: Replace the regular beef stock with a bone broth, skip Worcestershire sauce, or find a Paleo-friendly version. Also, use fresh onions and spices instead of onion soup mix.
  • Gluten-Free: Opt for a gluten-free beefy onion soup mix and Worcestershire sauce, and ensure your beef stock is gluten-free, too.
  • Whole30: Use compliant beef broth and season with Whole30-compliant spices, avoiding processed soup mix.
  • Vegetarian/Vegan: Substitute the beef with hearty vegetables like mushrooms or a meat alternative. Use vegetable stock and a vegan Worcestershire sauce. For a vegan onion soup mix, choose a brand without animal-derived ingredients.

Recipe Directions

  • Meat Prep: Cube your beef and add to the slow cooker.
  • Veggie Prep: Peel and cube onions, garlic, carrots, and potatoes.

Scaling The Recipe

Scaling the Slow Cooker Beef Stew with Onion Soup Mix is straightforward. Still, there are some guidelines to keep in mind for optimal results.

Scaling Up

  • Ingredients: Multiply the quantities by the number of servings you want to make. However, be cautious not to exceed the maximum capacity of your slow cooker.
  • Cooking Time: Surprisingly, the cooking time may not need significant adjustment, but checking for doneness earlier than the recipe indicates good.

Scaling Down

  • Ingredients: Halve or reduce the quantities to fit your needs.
  • Equipment: If scaling down significantly, consider using a smaller slow cooker for even cooking.
  • Cooking Time: While the 8-hour baseline generally holds, check periodically to prevent overcooking.

What Is Used For Garnishing? 

  • Fresh Herbs: Sprigs of fresh rosemary, thyme, or chopped parsley add vibrant color and infuse the dish with subtle aromatic notes.
  • Cheese: A light sprinkle of grated Parmesan or Pecorino Romano adds a rich, salty contrast to the hearty stew.
  • Citrus Zest: A dash of lemon or orange zest can brighten the flavors and add a delightful aroma.
  • Cracked Pepper: A freshly cracked black pepper sprinkle adds a finishing touch, giving the dish some heat and complexity.

Can I Make Slow Cooker Beef Stew With Onion Soup Mix In A Slow Cooker Or Instant Pot? 

You can prepare Slow Cooker Beef Stew with Onion Soup Mix in a traditional slow cooker and an Instant Pot, each offering unique advantages.

Slow Cooker

  • This appliance is excellent for a ‘set and forget’ approach. Combine all your ingredients and let them simmer for about 8 hours. 
  • The slow, steady heat brings out the flavors in a marvelous way.

Instant Pot

  • The Instant Pot can be a lifesaver if you’re short on time. Use the “Sauté” function for initial browning if desired, then switch to the “Slow Cook” or “Pressure Cook” settings. 
  • Pressure cooking will significantly reduce the cooking time to 35-40 minutes.

Can I Use Store Bought Broth, Or Should I Make My Own? 

Both store-bought and homemade broths can work well in your Slow Cooker Beef Stew with Onion Soup Mix. Still, each has its own set of advantages and considerations.

Store-Bought Broth

  • This option is convenient and time-saving. Opt for a low-sodium, organic version to better control the salt and flavor. 
  • Some high-quality store brands offer complex flavors that can enhance your stew.

Homemade Broth

  • Making your broth allows you to customize the flavors exactly to your liking. 
  • It’s often more nutritious and lacks the preservatives found in store-bought versions. However, it does require additional time and planning.

Can I Use Different Types Of Meat/Fish/Pasta/Vegetables For The Soup? 

  • Meat: Beyond beef, you can try lamb, pork, or chicken for a different flavor profile.
  • Fish: While less traditional for a stew, hearty fish like salmon or cod could offer a unique twist.
  • Pasta: Adding pasta like orzo or small shells is a quick way to fill the dish. Just be cautious about cooking times to avoid mushy pasta.
  • Vegetables: Feel free to add or substitute with veggies like zucchini, green beans, or mushrooms for extra nutrients and flavors.

Success Tips – Tips And Tricks For Making The Soup

It’s easy to run into some issues while cooking, so here are a few tips and tricks that might come in handy if you want to make this dish. These tips will make the dish more straightforward!

Make Sure It Cooks For Long Enough

  • Ensure you give this dish plenty of time to cook on low heat. We would not recommend using a high heat, as this will impact the finished result and will not be as enjoyable.
  • The long cooking time on low heat ensures the meat is wonderfully tender and nothing burns. 
  • Aim to get everything in the slow cooker in the morning if you have dinner early or near noon if you enjoy dinner later in the day.
  • You could also prep everything early and leave it to cook for over eight hours! This will make everything juicy and flavorsome, but check on it occasionally. 

Skip The Salt If You Want To Watch Your Sodium Intake

  • You should skip the extra salt if you need to watch your sodium intake. The onion mix is already high in sodium, so you might not need to add more. 
  • Opt for a low-sodium beef broth when shopping for ingredients to take this further. If you make your broth (which is a lot easier than you think), remember not to add additional salt to the product. 

Any Onion Mix Will Do!

  • You do not need to use a specific type of onion mix to make this recipe work. While many people enjoy the Lipton onion soup mix, you can use any generic brand.
  • Just ensure it has all the right flavors, and you will not run into an issue. 

Get Ready-Prepped Ingredients To Save Time

  • If you want to save more time when preparing this dinner, there are ways to do that.
  • Get pre-cut ingredients from the grocery store where you can, or use small ingredients like baby carrots rather than large ones. 
  • Alternatively, prepare as much as you can ahead of time. Some ingredients like carrots and beef can be chopped the day before. 
  • However, this does not work for everything. Things like onions and potatoes should not be prepped in advance, as they are also unlikely to keep. It is better to dice up on the day when you are making the dish.

  • Accompanying Beverage: A glass of red wine or a robust ale pairs wonderfully with the rich, meaty stew.

Perfect Side Dishes To Complement Slow Cooker Beef Stew With Onion Soup Mix

How Long Can We Store The Soup? 

If you end up with leftovers, you can easily store them to enjoy later on. You could refrigerate or freeze the food if you know you will not eat it within a few days. 

  • To refrigerate the leftovers, store them in an airtight container and keep them sealed. There, it should be suitable for up to five days. Ideally, you should enjoy your food within three days of refrigerating. 
  • To freeze, you can use a freezer-safe container or store the leftovers in bags. Make sure it has cooled down completely, then find a spot.
  • Frozen food is indefinitely safe to eat as bacteria cannot multiply, but aim to eat it within three months. After that point, the quality will degrade and might not have the same texture or appearance. 
  • If you freeze your leftovers, let them fully thaw out overnight in the refrigerator. Once thawed, you can reheat it in a saucepan on the stove on low heat. Allow 10–15 minutes (depending on the size of the portion). 
  • For the best results, use a meat thermometer to check the internal temperature of the food. 
  • You could also use a microwave to reheat your leftovers. Use a microwave-safe bowl and reheat the stew at 45-second intervals. Stir everything after every interval, and continue until the food is piping hot.

Can I Make The Soup In Advance? 

Slow Cooker Beef Stew with Onion Soup Mix is an excellent candidate for make-ahead meals. The flavors often meld and improve when allowed to sit, making it even more delicious the next day. 

Prepare the stew as directed and let it cool completely before transferring it to an airtight container. Store it in the refrigerator if you plan to consume it within 3-4 days or in the freezer for more extended storage, up to 2-3 months. Thaw and reheat thoroughly before serving.

What Can We Do With Leftovers? 

  • Shepherd’s Pie: Use the stew as a filling, topping it with mashed potatoes and baking until golden.
  • Stew Tacos: Shred the leftover beef and use it as a taco filling, some stew veggies, and your favorite toppings.
  • Rice Bowl: Serve the stew over a bed of cooked rice, perhaps with some added steamed vegetables or a drizzle of teriyaki sauce.
