Low Carb Crockpot Green Beans: Step-by-Step Instructions

Ingredients

These ingredients create a flavorful, low-carb side that works for keto, paleo, diabetic, and gluten-free diets:

• 2 pounds (900g) fresh green beans, washed, trimmed, and snapped in half

• 1 small yellow onion, finely chopped

• 4 cloves garlic, minced

• 6–8 slices uncured bacon, chopped (optional but adds flavor and richness)

• 1 cup chicken broth (preferably low-sodium and homemade or bone broth for extra nutrients)

• 2 tablespoons butter (optional, adds richness)

• Salt and freshly ground black pepper, to taste

• ½ teaspoon smoked paprika (optional, for depth and color)

• ½ teaspoon crushed red pepper flakes (optional, for a subtle kick)

Note: You can adjust flavorings based on dietary preferences. For a vegetarian version, omit bacon and use vegetable broth.

Tools You’ll Need

• A crockpot/slow cooker (4-quart or larger recommended)

• Cutting board and sharp knife

• Mixing bowl (optional, for pre-mixing)

• Slotted spoon or tongs (for serving)

Step-by-Step Instructions

Step 1: Prep the Green Beans

Why it matters: Fresh green beans cook more evenly and retain texture better than frozen.

1. Wash the green beans thoroughly under cold water to remove dirt and debris.

2. Trim the ends by cutting or snapping off the stem end (and tip, if preferred).

3. Snap or cut into halves, especially if the beans are long—this helps them fit into the crockpot and makes them easier to serve and eat.

Tip: Avoid cutting beans too small. Aim for bite-sized pieces for the best texture.

Step 2: Prep the Aromatics and Optional Bacon

Why it matters: Prepping and sautéing the aromatics and bacon (if using) unlocks deeper flavor.

1. Chop 1 small onion into fine dice.

2. Mince 4 cloves of garlic or press with a garlic press.

3. If using bacon:

   • Chop the bacon into small pieces.

   • Pre-sauté in a skillet over medium heat for 5–7 minutes, until the fat is rendered and the bacon is lightly crispy.

   • Drain on paper towels to remove excess grease.

   • You can either add the cooked bacon now or reserve some to sprinkle on top when serving for extra texture.

Optional step: If you want extra flavor, you can lightly sauté the chopped onion and garlic in a bit of bacon grease or butter before adding them to the crockpot.

Step 3: Layer the Ingredients in the Crockpot

Why it matters: Layering helps flavors distribute evenly during the slow cook.

1. Place the trimmed green beans into the crockpot.

2. Add the chopped onion and garlic over the beans.

3. Sprinkle in the bacon (if using).

4. Pour in 1 cup of chicken broth.

5. Add the butter, cut into small cubes, spreading across the top.

6. Season with salt, pepper, paprika, and red pepper flakes (if using).

   • Start with about ½ teaspoon of salt and ¼ teaspoon of pepper. You can adjust later once it’s cooked and flavors have developed.

Note: You don’t need to stir everything—slow cooking will blend the flavors naturally.

Step 4: Cook in the Crockpot

Why it matters: Low and slow = tender beans infused with flavor.

1. Cover and cook on LOW for 4–6 hours or HIGH for 2–3 hours.

   • Cooking on low yields a more tender, slow-simmered texture.

   • High heat is fine for a faster option, but check beans sooner to avoid overcooking.

2. Avoid opening the lid frequently—this lets out moisture and heat, which can increase cooking time.

Tip: If you’re new to crockpot cooking, check your beans around the 4-hour mark (on low) or 2-hour mark (on high). They should be fork-tender but not mushy.

Step 5: Taste, Adjust, and Finish

Why it matters: Final seasoning ensures the flavors pop.

1. Once the beans are tender, taste the cooking liquid and beans.

2. Adjust seasoning as needed—add more salt, pepper, or spices if desired.

3. If you reserved bacon, sprinkle it on just before serving for added crunch.

4. Optional: For a fresh touch, squeeze a bit of lemon juice or sprinkle chopped parsley over the finished dish.

Step 6: Serve and Enjoy

1. Use a slotted spoon or tongs to lift green beans from the crockpot, letting extra liquid drain.

2. Serve warm as a side dish to your favorite protein or main course.

Flavor and Serving Suggestions

Here are a few ways to adapt and serve your crockpot green beans:

• Southern-style: Add a smoked ham hock or diced smoked turkey instead of bacon.

• Garlic butter green beans: Use extra garlic and double the butter for rich flavor.

• Italian twist: Add sun-dried tomatoes, Italian seasoning, and a sprinkle of grated Parmesan before serving.

• Spicy: Add chopped jalapeño or double the crushed red pepper flakes.

• Vegetarian/Vegan: Use olive oil or vegan butter and vegetable broth, and skip the bacon.
