Why Cook with Cast Iron?
There are so many reasons to start with cast iron, whether you’re cooking on the grill, in the oven, or on the stovetop. Here are a few of our favorites:
- Even heat retention: Once it’s hot, it stays hot, perfect for searing meat or baking evenly.
- Durability: Cast iron lasts for generations if cared for properly.
- Flavor boost: A well-seasoned pan adds depth and richness to your food.
- Versatility: Works on the stovetop, oven, grill, campfire, and even over coals.
Seasoning Cast Iron
Seasoning is what makes cast iron nonstick and protects it from rust. It’s basically baked-on oil that bonds to the pan. Many cast-iron pans come pre-seasoned, but if yours isn’t, here are some tips on how to season it yourself.
How to Season:
- Wash & Dry: Start with a clean, dry pan (use mild soap if needed).
- Oil It: Rub a thin coat of neutral oil all over—inside, outside, and handle (we recommend using beef tallow, but you can also use another oil, such as grapeseed, canola, or vegetable oil). Wipe away excess with a paper towel.
- Bake It: Place the pan upside down in a 450°F oven or on your Traeger grill. Put foil underneath to catch drips. Bake for 1 hour.
- Cool & Repeat: Let it cool, then repeat 2–3 times for a tough, glossy seasoning.
Pro tip: Every time you cook with a little oil or fat, you’re reinforcing that seasoning layer.
Cleaning Cast Iron
Contrary to myths, cast iron isn’t hard to clean.
- Skip the soap (most of the time): Hot water and a firm scrub pad or metal, chain-mail scrubber usually do the trick.
- Stubborn stuck bits: Scrub with coarse salt and a splash of water, then rinse.
- Dry immediately: Prevent rust by towel drying, then placing on low heat to evaporate moisture.
- Oil it after cleaning: Rub on a light layer of oil or tallow before storing.
Cooking with Cast Iron
Here’s where cast iron shines—hot, even, and versatile.
On the Grill (Traeger or traditional): Perfect for searing steaks, cooking fajitas, or baking skillet cornbread with smoky flavor.
On the Stovetop: Ideal for searing meats, sautéing veggies, or frying eggs. Preheat slowly to avoid hotspots.
In the Oven: Bake bread, casseroles, cobblers, and more. Retains heat beautifully, making it excellent for golden crusts.
Tips & Tricks for Success
- Preheat the pan: Always give it time to heat up before adding food.
- Don’t overcrowd: Food sears better with space.
- Acidic foods: You can cook tomatoes or wine sauces in cast iron, but don’t let them sit too long or they’ll strip seasoning.
- Use the right tools: Metal spatulas are fine and actually help keep the seasoning smooth.
- Store properly: Keep in a dry place; slip a paper towel between stacked pans to absorb moisture.
Cast Iron Favorites on the Grill
From savory dips to sizzling desserts, cast iron shines on the Traeger. We’ve used it for our smoky queso (the ultimate party starter), our juicy peach cobbler (aka dump cake), our skillet cookie (crispy edges, gooey middle), and our spiced apple dump cake (bubbly apples with a golden topping).
Each recipe proves just how versatile cast iron can be—holding heat evenly, picking up subtle smoke, and making cleanup a breeze!
Here’s why each one works so well in cast iron:
Spiced Apple Dump Cake
Why This Works in Cast Iron:
Cast iron holds steady heat, which means the apple filling gets bubbly while the buttery, spiced cake topping crisps up beautifully without burning. On the Traeger, the skillet also captures just the right amount of smoky flavor, turning a simple dump cake into a rustic, crowd-pleasing dessert. Plus, cast iron makes for an easy, one-pan presentation—straight from grill to table.
Smoked Queso
Why This Works in Cast Iron:
Cast iron holds heat like no other, which keeps queso creamy and melty while it absorbs smoky flavor from the grill. The skillet also makes for easy serving—straight from smoker to table, it stays warm long after it’s pulled off the heat.
Peach Cobbler (aka dump cake)
Why This Works in Cast Iron:
Juicy peaches bubble up beautifully in cast iron, while the skillet helps the cobbler topping bake into a golden, crisp crust. The even heat ensures the fruit cooks through without scorching, and the rustic presentation is perfect for sharing right out of the pan.
Skillet Cookie
Why This Works in Cast Iron:
Cast iron gives this cookie its signature contrast—crispy, caramelized edges with a soft, gooey center. The pan holds steady heat for even baking, and once you top it with ice cream and dig in, it’s the ultimate crowd-pleasing dessert.
Smoked Mac and Cheese
Why This Works in Cast Iron:
Cast iron holds heat evenly, which is perfect for creamy sauces and baked pasta. On the grill, smoked mac and cheese develops a golden, crispy top while the smoke infuses the cheese with incredible depth of flavor. The skillet keeps it bubbling hot from the first bite to the last, making it the ultimate comfort food for backyard gatherings.
Cast Iron 2-Ingredient Biscuits
Why This Works in Cast Iron:
Cast iron’s steady, even heat creates biscuits that are crisp on the bottom, fluffy inside, and golden on top. In the oven, the skillet locks in heat for consistent baking. On the grill, it adds a hint of smoky flavor you just can’t get indoors.
