Ingredients You’ll Need
To keep this recipe authentic and incredibly cost-effective, you only need these four pantry and fridge staples. This makes it an excellent option for budget-conscious meal planning and minimal grocery shopping.
- 2 pounds ground beef: For the best balance of flavor and moisture, we recommend using 80–85% lean beef.
- 4 cups peeled and diced russet potatoes: This is approximately 3–4 medium-sized potatoes.
- 2 cups diced yellow onion: About 2 medium onions, finely chopped.
- 2 cans (28 ounces each) tomatoes: You can use crushed tomatoes for a thicker texture or diced tomatoes with their juice for a more traditional stew feel.
Step-by-Step Instructions
Follow these simple, professional steps to ensure your stew turns out perfectly every single time.
- Brown the Beef: In a large skillet over medium-high heat, brown the ground beef, breaking it into small crumbles as it cooks. Continue cooking for 7–10 minutes until no pink remains and most of the liquid has evaporated. Pro tip: For a lighter stew, drain off any excess grease at this stage.
- Layer the Slow Cooker: Spread the browned ground beef in an even layer at the bottom of a 5–6 quart slow cooker. Next, layer the diced potatoes over the beef, followed by an even scattering of diced onions. Important: Do not stir the ingredients yet! Keeping them in layers allows the potatoes and onions to steam and cook perfectly within the tomato broth.
- Add the Tomatoes: Pour the canned tomatoes (including all the juice) over the top of the onions and potatoes. If the mixture looks too thick, gently shake the slow cooker or use a spoon to lightly press the ingredients down so the liquid settles around everything.
- Slow Cook to Perfection: Cover with the lid and cook on LOW for 7–8 hours or on HIGH for 4–5 hours. You will know it is ready when the potatoes are fork-tender and the onions have softened into the broth.
- The Final Stir: Once the cooking time is complete, gently stir the stew from the bottom to combine the beef, potatoes, onions, and tomatoes into a rich, dark, tomato-based broth. Taste and add a pinch of salt and pepper if desired.
Why This Recipe is Loved
This Mulligan Stew has become a legendary family staple because it strikes the perfect balance between frugal living and gourmet comfort. It honors the “spirit of the stew”—a simple, honest meal that tastes even better as the flavors marry over several hours of slow cooking. Because it is incredibly forgiving, it is an ideal recipe for beginners or anyone looking to simplify their dinner routine without sacrificing quality.
Pro Tips for Perfecting Your Stew
For a Thicker Consistency
If you prefer a thicker, heartier gravy, take a few of the cooked potatoes and mash them against the side of the slow cooker, then stir them back in. Alternatively, leave the lid slightly ajar for the last 30 minutes of cooking on HIGH to allow some liquid to evaporate.
A Trick for Picky Eaters
If you have children who are sensitive to textures, dice the potatoes smaller and the onions very finely. After 8 hours of slow cooking, the onions will almost “disappear” into the delicious, flavorful broth.
Elevate the Flavor
For a little extra “zip,” swap the plain tomatoes for fire-roasted tomatoes or diced tomatoes with green chilies. This adds a subtle depth and a hint of smoky sweetness.
Maximize Your Savings
This is a fantastic “stretch” meal. To make it even more filling for a growing family, serve the stew over cooked rice, elbow macaroni, or wide egg noodles.
Serving Suggestions
To turn this simple stew into a complete, restaurant-quality feast, try these pairings:
- Crusty Bread: A warm baguette or garlic bread is perfect for mopping up every last drop of the savory tomato broth.
- Fresh Greens: A crisp side salad with a light vinaigrette provides a refreshing contrast to the rich, heavy stew.
- Elegant Garnish: Top each bowl with a sprinkle of fresh parsley or a little shredded parmesan cheese for an extra touch of sophistication.
