Mushroom Free Paleo Cajun Shrimp & Sausage Skillet with Lime

Bold, smoky, and bright with citrus, this cast iron skillet dinner is the kind of weeknight meal that looks and tastes like you put in way more effort than you actually did. Andouille sausage gets seared until the cut sides are deeply caramelized, shrimp are coated in a punchy homemade Cajun blend, and colorful bell peppers pick up a little char along the way — every element earns its place in the pan. The spice mix comes together from pantry staples like smoked paprika, cayenne, thyme, and oregano, so you're in full control of what goes into the dish without relying on any pre-made seasoning packets that might sneak in unwanted ingredients. A hit of fresh lime juice and zest right at the end cuts through the richness and ties everything together in a way that feels almost restaurant-worthy. Because the whole thing is built on whole proteins, vegetables, and avocado oil, it fits naturally into a grain-free, legume-free way of eating without any awkward substitutions. If you're cooking for someone who needs to avoid fungi entirely, this recipe is completely clean — no mushrooms, no mushroom-derived powders, nothing hiding in the sauce. Scatter some fresh cilantro on top and serve with extra lime wedges for a finish that's as pretty as it is delicious.
