8 Keto Bell Pepper Stir Fry Recipes

Hey there, fellow foodie! Are you stuck in a dinner rut, scrolling endlessly through recipe feeds that all look the same? Or maybe you’re doing the keto thing and miss flavor? I’ve been there. Keto can get a little repetitive (hello, endless eggs and bacon). That’s why I am completely obsessed with bell pepper stir-fries. They are vibrant, packed with crunch, and ridiculously versatile. Best of all? They respect your low-carb boundaries without sacrificing an ounce of taste. We’re talking 10-minute dinners that taste like they took an hour. Who has time for complicated stuff on a Tuesday, anyway? Let’s fix your dinner menu, shall we?

7. Simple Sausage & Cabbage Sheet Pan (with Peppers!)

Technically, this isn’t a “stir-fry” in a wok. But it is a “stir-everything-onto-one-pan” dinner that tastes like a stir-fry, and I am a massive fan of simplifying life. Let’s roast all that goodness instead.

Ingredients

• 1 lb Smoked Kielbasa Sausage (check label for low sugar!)
• 1 small Cabbage, chopped into chunks
• 2 large Bell Peppers (one red, one green), chopped into large chunks
• 1 small Onion, chopped into large chunks
• 2 tbsp Olive Oil
• 1 tbsp Everything Bagel Seasoning (optional, but awesome)
• Salt and Black Pepper to taste

Step-by-Step Instructions

1. Preheat your oven to 425°F (220°C).
2. Slice the kielbasa sausage into 1-inch coins.
3. On a large, rimmed baking sheet, combine the sausage coins, chopped cabbage, large bell pepper chunks, and onion.
4. Drizzle everything generously with olive oil and sprinkle with Everything Bagel Seasoning (or just salt/pepper).
5. Toss everything directly on the pan to ensure it’s all evenly coated. Spread the mixture in a single, even layer. Don’t overcrowd the pan, or it will steam instead of roast! Use two pans if needed.
6. Roast for 20-25 minutes, stirring halfway through, until the sausage edges are browned and the cabbage and peppers are caramelized and tender. Serve immediately.

Why You’ll Love It

This is the ultimate hands-off “stir-fry” dinner. The high oven heat roasts the peppers and cabbage perfectly, bringing out their natural sweetness. Cleaning one baking sheet is a lot better than cleaning a wok, just saying. It’s perfect for meal prep.
