How to Make Slow Cooker Garlic Butter Beef with Potatoes

Okay, get ready, because making this Slow Cooker Garlic Butter Beef with Potatoes is seriously the easiest thing ever. You basically just throw everything in and let your slow cooker do all the heavy lifting. Trust me, it tastes like you slaved away for hours! It’s a fantastic way to get a hearty meal on the table with minimal Fuss, kind of like a more robust version of this hearty gluten-free beef stew.

Step 1: Prepare the Slow Cooker

First things first, grab your slow cooker. A quick spray with some non-stick cooking spray on the bottom is all you need to make sure nothing sticks. Itโ€™s such a simple step, but it makes cleanup so much less of a chore!

Step 2: Combine Main Ingredients

Now for the fun part! Dump your pretty beef stew meat right into the slow cooker. Then, add in those baby potatoes youโ€™ve halved if they were a bit chunky. Next, sprinkle over that whole packet of onion soup mix โ€“ itโ€™s like a secret flavor booster! Follow that up with your garlic powder, sea salt, black pepper, and that delicious minced garlic. Don’t forget to scatter those 4 tablespoons of butter pieces all over the top; they’ll melt into pure gold.

Step 3: Add Liquids and Butter

Pour in your water or beef broth. This is going to help everything steam and get super tender, and it creates a lovely sauce base. Just nestle it in with the rest of the goodness.

Step 4: Cook and Add Final Ingredients

Now, pop the lid on tight. You can cook this on high for about 3-4 hours, or if you have more time, low for 6-8 hours is fantastic too. If youโ€™re adding green beans โ€“ and seriously, you should! โ€“ toss them in during the last hour or two of cooking. This way, they stay nice and bright and have a little bit of snap, not mushy. If you want an extra layer of richness, go ahead and toss in those extra 2 tablespoons of butter with the green beans.

Tips for Perfect Slow Cooker Garlic Butter Beef with Potatoes

Okay, so making this Slow Cooker Garlic Butter Beef with Potatoes is pretty foolproof, but a few little tricks can make it absolutely spectacular. As someone who lives and breathes meal planning (thanks, Michael Davis, MS, RD!), Iโ€™ve learned a thing or two about getting the most out of your slow cooker. Think of these as your secret weapons for perfection!

Choosing the Right Cut of Beef

For this dish, beef stew meat is your best friend! Look for cuts that have a good amount of marbling โ€“ those little streaks of fat. They break down during the long, slow cooking time, making the beef incredibly tender and juicy. Cuts like chuck roast, trimmed and cubed, work wonders. They might seem a bit tough initially, but the slow cooker works its magic, transforming them into melt-in-your-mouth goodness.

Potato Preparation for Even Cooking

Those baby potatoes are great because they’re small, but if some are on the larger side, definitely halve or even quarter them. This ensures they cook at the same rate as the beef. Nobody likes biting into a potato that’s still hard in the middle when the beef is fall-apart tender! Just a quick cut makes all the difference.

Adjusting Cooking Times

Every slow cooker is a little different, you know? Some run hotter than others. So, while the times Iโ€™ve given (3-4 hours on high, 6-8 hours on low) are a great guide, always give it a peek. Your beef should be super tender and easily shredded with a fork, and the potatoes should be fork-tender too. If youโ€™re adding veggies like green beans, make sure theyโ€™re added in that last hour or so so they donโ€™t turn to mush. For more general wisdom, a quick read of my crockpot cooking tips might be helpful!

Ingredient Notes and Substitutions

Let’s chat real quick about a few things in the recipe and what you can do if you don’t have exactly what’s listed. Don’t stress if you need to swap something out; this dish is pretty forgiving!

Beef Alternatives

Beef stew meat is my go-to because it’s budget-friendly and gets super tender. But if you can’t find it or want something different, chuck roast cut into cubes works beautifully. You could even use leaner cuts like sirloin, but just be aware they might not get *as* melt-in-your-mouth as a fattier cut.

Potato Choices

Baby potatoes are awesome because they’re already small and cook up nicely. Yukon Golds or red potatoes are great substitutes โ€“ just chop them into bite-sized pieces, about an inch or so, so they cook evenly. You want them done, but not completely falling apart!

Onion Soup Mix Magic

That packet of onion soup mix is pure genius for flavor! If you don’t have it, no worries. Just mix about 1/4 cup dried minced onion, 1 tablespoon onion powder, and maybe a pinch of sugar and some salt and pepper. It won’t be *exactly* the same, but itโ€™ll still be yummy!

Serving Suggestions for Slow Cooker Garlic Butter Beef with Potatoes

This Slow Cooker Garlic Butter Beef with Potatoes is pretty much a complete meal in itself, but who doesn’t love a little something extra? Itโ€™s so hearty and comforting, I love serving it with something to soak up all that garlicky, buttery goodness. Some fluffy restaurant-style mashed potatoes are always a hit, though honestly, the potatoes already in the dish are pretty amazing! A simple side of crusty bread is also perfect for mopping up any leftover sauce. If you want to add a bit of freshness, some steamed broccoli or a light green salad works wonders.

Storage and Reheating

Got leftovers? Lucky you! Store any leftover Slow Cooker Garlic Butter Beef with Potatoes in an airtight container in the fridge for up to 3-4 days. When you’re ready to reheat, just pop a portion into a microwave-safe dish and heat gently until warm throughout. You can also reheat it slowly on the stovetop over low heat, stirring occasionally, to really bring back that luscious sauce.

Frequently Asked Questions about Slow Cooker Garlic Butter Beef with Potatoes

Got questions about making this amazing Slow Cooker Garlic Butter Beef with Potatoes? I totally get it! It’s one of those super comforting dishes that always sparks a few good queries. Here are some of the most common things people ask:

Can I use a different cut of beef?

Absolutely! While beef stew meat is my top pick for its tenderness after slow cooking, you can totally use chuck roast cut into cubes. Just make sure you trim off any large chunks of fat before you start. Other cuts might work, but they may not get quite as fall-apart tender.

How do I thicken the sauce if it’s too thin?

No worries if your sauce isn’t as thick as you like! The easiest way is to mix a tablespoon or two of cornstarch with an equal amount of cold water until it’s smooth. Then, stir that slurry into the slow cooker during the last 30 minutes of cooking and let it simmer until it thickens up. You can also just let it cook uncovered for the last 30 minutes to let some of the liquid evaporate.

Can I make this ahead of time?

You sure can! This is one of those recipes that’s perfect for making ahead, almost like a fantastic meal prep idea. You can assemble everything in the slow cooker insert the night before, cover it, and store it in the fridge. Just pull it out in the morning and pop it in the base to start cooking. Or, cook it fully, let it cool, and then store it in the fridge for up to 3 days. Reheat gently on the stovetop or in the microwave.

What if I don’t have an onion soup mix packet?

No problem at all! You can totally fake it. Mix about 1/4 cup of dried minced onion with 1 tablespoon of onion powder, 1 teaspoon of garlic powder (since you’ve already got it!), and season with a bit of salt and pepper. It gives you that savory oniony flavor that the packet provides so you still get all that deliciousness in your Slow Cooker Garlic Butter Beef with Potatoes.
