This first step is optional, but SO worth it to lock flavor into your meat and give it that perfect, tender consistency that you can cut with a spoon. Grab a large skillet or fry pan and drizzle 2 T of olive oil over med-high heat. Pat your beef stew meat dry with a paper towel (this helps it get a nice sear), then season generously with salt and black pepper. Sear the meat in batches, cooking for about 2-3 minutes per side until browned. This extra step is recommended, but can be skipped if you’re short on time.
Transfer meat to you slow cooker. Pour 1/4 c beef broth and the minced garlic into the hot skillet and simmer for 1 minute while stirring. Use the back of a wooden spoon or spatula to scrape all of the flavor bits off the bottom of the pan. Pour into crockpot over top of the meat.
Grab a 1lb bag of mini Yukon gold potatoes and rinse with a fruit and veggie wash (optional) and water. Since we are going to leave the skin on the potatoes, I like to scrub with a soft brush like this to make sure I get all remnants of dirt off potatoes. Cut each potato into quarters and drop into the pot with the seared beef. Peal 6 carrots and slice into coin shapes roughly 1/2" thick. Add to slow cooker along with 6oz tomato paste and 1T worcestershire sauce. Pour in the remaining 3 cups of beef broth and give everything a good stir to combine.
My husband doesn't care for chunks of onion in his food, but I definitely don't want to lose that flavor, so my hack is to simply place half of a peeled onion in the center of my slow cooker, and let its flavor meld into the stew as it cooks. Note: if you don't mind onion, go ahead and simply dice it up and drop it into the crock pot with everything else.
Add 3 bay leaves into the pot (I like to spread them out a bit in different corners), and place lid on top.
Set your slow cooker to low heat and cook for 7-8 hours, or on high heat for 4-5 hours.
About 10 minutes before serving, open the lid and remove the onion and the bay leaves. Stir in 1 cup of frozen peas. The heat will warm them up quickly without making them mushy.
Take a peak at the amount of liquid in your stew. If you want to thicken it up, make a cornstarch slurry by whisking 2 tablespoons of cornstarch with 2 tablespoons of cold water in a medium bowl. Stir the slurry into the stew. This will give it a thicker, gravy like consistency to your stew. If you prefer it to be more broth like, you can skip this step.
Ladle into bowls. I like to serve with crusty bread and butte.
