Ingredients
1½ pounds baby potatoes (red, yellow, or mixed), halved if large
1 pound fresh green beans, trimmed
1 cup Italian salad dressing (zesty or regular)
Step-by-Step Instructions
Step 1: Prepare the Vegetables
Rinse the baby potatoes and pat them dry. If any potatoes are larger than bite-size, cut them in half so they cook evenly.
Rinse the green beans and trim off the stem ends.
Step 2: Layer the Vegetables in the Slow Cooker
Add the potatoes to the bottom of a 4- to 6-quart slow cooker. Layer the green beans on top of the potatoes. This helps the potatoes cook evenly while allowing the green beans to stay tender, not mushy.
Step 3: Add the Italian Dressing
Pour the Italian dressing evenly over the potatoes and green beans. Most of the vegetables should get lightly coated. Give everything a gentle toss if needed, but it doesn’t have to be perfectly mixed.
Step 4: Cook
Cover the slow cooker with the lid and cook:
LOW: 5–6 hours
HIGH: 2½–3½ hours
The dish is done when the potatoes are fork-tender and the green beans are cooked to your preferred softness.
Step 5: Finish and Serve
Once cooked, gently stir the vegetables so they’re coated in the flavorful cooking juices. Taste and, if needed, add a pinch of salt or black pepper.
Spoon into a serving bowl and drizzle a little of the cooking liquid over the top before serving warm.
Variations & Helpful Tips
Extra Flavor (Still Simple): Add 1–2 minced garlic cloves or 1 teaspoon Italian seasoning. A sprinkle of grated Parmesan or Romano cheese before serving adds a savory finish.
For Picky Eaters: Use half green beans and half carrot coins for a sweeter balance. Cutting the potatoes smaller also makes them extra soft and buttery.
Make It a Full Meal: Add sliced cooked Italian sausage, diced ham, or shredded rotisserie chicken during the last 30 minutes of cooking.
Different Vegetables: Swap green beans for broccoli or cauliflower during the last 1½–2 hours. Frozen green beans work too—add about 30 extra minutes on LOW.
Lighter Option: Use light or fat-free Italian dressing. If flavor is mild, finish with a squeeze of fresh lemon juice.
Make-Ahead Tip: Prep the vegetables the night before and store them in the fridge. In the morning, just add them to the slow cooker and pour on the dressing.
Storage & Reheating
Refrigerator: Store leftovers in an airtight container for up to 3 days
Reheat: Warm in the microwave or on the stovetop with a spoonful of the cooking liquid
Freezing: Not recommended, as the potatoes may become grainy
