Ingredients for green bean and potato crock pot
Six core ingredients create this herbed butter masterpiece—simple yet restaurant-worthy.
| Ingredient | Amount | Notes |
|---|---|---|
| Baby Potatoes 🥔 | 2 lbs | Yukon gold preferred, halved |
| Fresh Green Beans 🌱 | 1 ½ lbs | Trimmed, cut into 2-inch pieces |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for crust |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Chopped finely, stems removed |
| Fresh Parsley Leaves 🌿 | ½ cup | Chopped, for garnish |
| Garlic Cloves 🧄 | 4 cloves | Minced, for depth |
| Chicken Broth 💧 | 1 ½ cups | Low-sodium preferred |
| Olive Oil 🫒 | 1 tbsp | For tossing potatoes |
| Sea Salt 🧂 | 1 ½ tsp | Kosher preferred, adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Bacon 🥓 | 4 oz | Optional, chopped for protein boost |
| Dried Rosemary 🌿 | 1 tsp | Crushed, for earthy aroma |
| White Wine 🍷 | ½ cup | Dry, optional for richness |
The potatoes and green beans form the foundation, so choose Yukon gold potatoes for their creamy texture and fresh green beans with vibrant color. Costco or Trader Joe’s often have pre-trimmed green beans, saving prep time. For the herbed butter, unsalted butter is a must—it lets the herbs shine without competing saltiness. Fresh thyme and parsley from the grocery store’s produce section (not the dried aisle) add the brightest flavor. If you’re adding bacon, grab thick-cut for better texture during cooking.
No fresh thyme? Dried thyme at one-third the amount works, but fresh is ideal. Swap white wine for extra chicken broth if avoiding alcohol. For a vegan option, use vegetable broth and olive oil-based butter substitute. The garlic can be pre-minced from a jar, but freshly minced adds depth. If you’re meal prepping, double the ingredients—they reheat beautifully. The dried rosemary should be crushed between your fingers to release its aroma before adding to the slow cooker.
Store any leftovers in an airtight container for up to 4 days in the fridge, or freeze for 3 months. The herbed butter crust can be prepped ahead and refrigerated until ready to use—just let it sit at room temperature for 10 minutes before sprinkling. For a crispier crust, broil for 2-3 minutes at the end. This dish reheats best covered with foil to prevent drying out, then uncovered for the final crisp under the broiler.
Why You’ll Love This Recipe
- Ditch the Chopping: I’ll be real—this recipe only needs two things chopped: green beans (snapped, not sliced) and baby potatoes (halved, if you’re feeling fancy). The rest? Butter, thyme, parsley—just toss and forget. Even my kids can handle the prep while I stir the crockpot.
- Butter-Kissed Magic: That golden butter bath on the potatoes? It’s everything. The thyme leaves melt into the butter, the parsley brightens it up, and the green beans stay crisp-tender instead of mushy. Honestly, the first time I tasted it, I nearly licked the pot clean.
- Lunchbox Hero: Between us, this is my go-to for meal prep. The flavors get even better the next day, and it reheats like a dream. Pack it cold for work lunches or serve it warm for a picnic—no one will guess it’s just potatoes and green beans. (Yes, even on a Tuesday night.)
- Budget Win: Baby potatoes and green beans are cheap, but they feel special. A stick of butter and a handful of fresh herbs make this taste like a restaurant side without the price tag. I’ve made this for 10 people on a tight budget, and no one complained—zero waste, all satisfaction.
Step-by-step instructions for green bean and potato crock pot recipe
Here’s how to create a perfectly balanced one-pot dish with tender potatoes and crisp-tender green beans.
Prepare the Potatoes and Green Beans
Begin by halving the 2 lbs of baby potatoes, leaving the skins intact for texture. Toss them in a bowl with the 1 tablespoon of olive oil, 1 teaspoon of the sea salt, and 0.25 teaspoon of the black pepper. This coating ensures even browning and flavor distribution when we add them to the crock pot later.
Next, trim the ends from the 1.5 lbs of fresh green beans and cut them into 2-inch pieces. Set these aside in a separate bowl. The fresh cut will help release their natural sweetness during cooking. If using the 4 oz of bacon, chop it into small pieces and set aside for the next step.
Create the Herbed Butter Crust Mixture
In a small bowl, combine the 0.5 cup of cold, cubed unsalted butter with the 1 tablespoon of finely chopped fresh thyme leaves, 1 teaspoon of crushed dried rosemary, and the 4 cloves of minced garlic. Mix gently with a fork until the herbs are evenly distributed throughout the butter.
This herbed butter will create the signature crust on top of your dish. The cold butter ensures it stays in chunks rather than melting completely, which is crucial for that golden, crispy finish. If using the white wine, add 0.25 cup now and mix lightly—this adds depth but isn’t essential.
Layer and Cook in the Crock Pot
Place the halved potatoes in the bottom of your crock pot, arranging them in a single layer. Pour the 1.5 cups of chicken broth over the potatoes, then add the green beans on top. If using bacon, sprinkle the chopped pieces evenly over the green beans.
Cook on low heat for 4 hours. The potatoes should be fork-tender with no resistance when pierced, and the green beans should be bright green and just tender—not mushy. If the potatoes are cooking faster than the green beans, you can transfer them to a plate after 3 hours and return them after the green beans have finished.
Add the Herbed Butter and Finish
Remove the crock pot from heat and carefully spread the herbed butter mixture evenly over the top of the potatoes and green beans. The butter should melt slightly but still maintain some texture for that coveted crust. If the mixture looks too dry, sprinkle with 1 tablespoon of water and stir gently.
Return the crock pot to low heat and cook for an additional 15-20 minutes. This final step creates the crispy, golden crust while keeping the vegetables tender. Watch closely during the last 5 minutes to ensure the butter doesn’t burn—it should be golden brown with slight browning on the edges.
Garnish and Serve
Transfer the dish to a serving platter and sprinkle with the remaining 0.25 teaspoon of black pepper and the 0.5 cup of chopped fresh parsley leaves. The parsley adds a fresh contrast to the rich herbed butter. Serve immediately with crusty bread to soak up any remaining juices.
Each bite should deliver tender potatoes with a crispy exterior, bright green beans, and layers of herbed butter flavor. The dish holds well for 2-3 days in the refrigerator, though the crust will soften slightly when reheated. For best results, serve straight from the crock pot while everything is at its peak.
Pro Tips For Making Green Bean And Potato Crock Pot
- HALVE THE POTATOES FIRST: Baby potatoes take forever to soften in a crock pot—learned that after one soggy, undercooked batch. Cut them in half before adding, even if the recipe says not to. The surface area cooks faster, and you’ll avoid that gummy texture no one wants.
- SALT THE BEANS NOW: Fresh green beans wilt and lose flavor if you wait to season. Toss them with a pinch of salt and a drizzle of cold water right after trimming, then let them sit for 10 minutes. This crisps the edges and keeps them vibrant—trust me, it’s worth the extra step.
- LOW AND SLOW ISN’T LOW: Most recipes say “low heat,” but I’ve found 250°F (not the “low” setting) is the sweet spot. Too low, and the butter separates into a greasy mess; too high, and the potatoes turn to mush. Check your crock pot’s manual—some “low” settings are deceptive.
- BUTTER LAST, NOT FIRST: I used to add butter at the start, and it’d just melt into a sad puddle. Instead, stir in a pat of cold butter and a splash of broth during the last 15 minutes. It emulsifies into the veggies, giving that rich, saucy finish without curdling. Works like magic.
Common mistakes when making your green bean and potato crock pot
Overcooking Vegetables
The biggest mistake is letting your green beans turn mushy or your potatoes disintegrate. Potatoes should be fork-tender with slight resistance (4 hours on low), while green beans should stay crisp-tender with vibrant color.
I’ve ruined this dish by keeping it in too long—always check at 3 hours and adjust if needed. The crock pot’s gentle heat can be deceivingly powerful. 🌱
Skipping the Butter Crust
Many people stop after the slow cooking phase, missing the magic of the herbed butter crust. This isn’t just decoration—it’s what transforms your dish from good to restaurant-quality. Spread the cold butter mixture evenly and cook it uncovered for those final 15-20 minutes to get proper browning.
I once served this without the crust and got blank stares from my family.
Uneven Liquid Distribution
Pouring all the broth directly on the potatoes can create steam pockets that leave green beans dry. Instead, arrange potatoes in a single layer first, then pour broth over them, and add green beans on top.
This ensures even moisture distribution. I learned this the hard way when I got half-cooked green beans and overcooked potatoes in the same pot. 💧
Ignoring the Low Heat Rule
Some people crank their crock pots to high for faster cooking, but this leads to uneven doneness and potential burning. The slow, gentle heat on low is what develops the flavors properly.
If you’re short on time, use high for 2.5 hours max, but monitor closely. I’ve seen perfectly good dishes ruined by impatience and high heat.
Using Pre-Cooked Potatoes
Starting with pre-boiled or microwave-steamed potatoes will make them turn to mush in the crock pot. Always use raw, halved potatoes for proper texture. The slow cooker’s moisture will handle all the cooking needed. I once used leftover mashed potatoes in this recipe—don’t make that mistake! 🥔
Forgetting the Final Rest
After adding the herbed butter, resist the urge to serve immediately. Let it sit covered for 5 minutes to allow flavors to meld. This simple step makes a huge difference in taste.
I’ve caught myself serving it too soon and regretting it later—always let that butter work its magic before diving in.

Frequently asked questions
Can I make this recipe without a crock pot?
Yes! Use an oven instead: Toss halved potatoes with olive oil, salt, and pepper, then spread in a baking dish. Pour broth over them, add green beans, and bake at 375°F for 45-50 minutes until tender. Top with herbed butter and broil for 5 minutes to crisp. The texture will be slightly different but still delicious.
How do I adjust this for meal prep?
Double the ingredients and cook as directed. Store in an airtight container for up to 4 days in the fridge. Reheat covered with foil for 10-15 minutes on low heat, then broil for 2 minutes to restore the crust. Add fresh parsley after reheating for brightness.
What if I don’t have fresh herbs?
Use dried herbs at one-third the amount (e.g., 1/3 tsp dried thyme for 1 tbsp fresh). Crush dried rosemary between your fingers to release flavor. For parsley, skip it or use dried—but fresh adds the best pop of color and freshness.
Can I add other vegetables?
Yes! Try adding 1 cup of diced carrots or 1/2 cup of corn kernels with the green beans. They’ll cook at a similar rate. Avoid leafy greens like spinach—they’ll wilt too quickly. Adjust cooking time by 15-20 minutes if adding denser veggies.
Why is my butter crust not crispy?
Cold butter is key—don’t melt it before adding! Spread it evenly and cook uncovered on low for 15-20 minutes to brown. If it softens too soon, broil for 2-3 minutes at the end. Avoid overcrowding the crock pot, which traps steam.
