Cheesy Ground Beef Stuffed Poblano Peppers

These cheesy ground beef stuffed poblano peppers bring a hearty Tex-Mex feel to the dinner table. Poblano halves become tender in the oven while seasoned beef and tomato sauce make a savory filling, and cheddar-Jack melts over the top with browned spots.

The recipe keeps the focus on familiar ingredients and a satisfying contrast of textures: soft pepper, richly seasoned beef, and gooey cheese. A few small choices, from selecting peppers that are close in size to draining excess fat when needed, help the dish bake evenly.

Pick peppers that will bake evenly

Look for large poblanos that are similar in size and shape. When the halves are roughly alike, they are more likely to turn tender at the same pace. Especially large peppers may need a little longer in the oven, so check their tenderness along with the cheese rather than judging doneness by the browned topping alone.

Halving the peppers lengthwise creates open boats for the beef filling. Remove the stems, seeds, and membranes, then arrange the halves cut-side up in an evenly sized baking dish. Keeping them upright helps hold the filling in place. Poblano peppers bring a mild chile flavor that works well with the cumin, chili powder, and tomato sauce.

Build a savory beef filling

Yellow onion and garlic give the ground beef a familiar savory base. Let the onion cook in olive oil until softened, stirring as it cooks. Add the beef and break it into small crumbles so it browns more evenly and is easy to spoon into the peppers. Once browned and cooked through, drain excess fat if needed; too much can make the filling greasy.

Chili powder and ground cumin season the beef with warm, earthy notes, while kosher salt and black pepper round out the flavor. Stir in the tomato sauce so it coats the crumbles and brings moisture to the filling. Keep the mixture cohesive rather than watery: it should sit neatly in the pepper halves instead of spilling over their edges.

Use the cheese in two layers

Cheddar-Jack brings both a familiar cheddar flavor and a smooth melt. Stir some of the cheese into the beef mixture so the filling has cheesy bites throughout. Add the rest over the filled peppers, where it melts into a generous top layer.

Keep the filling and topping portions separate as you assemble the dish. Spreading the topping across the peppers helps each half get a share of melted cheese. Bake uncovered so the surface can brown in spots while the peppers soften. The peppers are ready when they are tender and the cheese is melted with browned patches.

Watch tenderness as the dish bakes

Pepper size affects how quickly the halves become tender, so use their texture as your guide. If you choose especially large poblanos, they may need a few extra minutes in the oven. The cheese should be melted and browned in spots, but that color alone does not tell you whether the pepper is tender.

Serve the stuffed peppers hot from the oven. The filling should stay nestled inside each half, with tomato sauce binding the beef and melted cheese joining the top to the savory mixture below. If a pepper shifts while you spoon in the filling, settle it back cut-side up in the baking dish before baking.

Frequently Asked Questions

How do you know when the stuffed poblanos are done?

Check for tender pepper flesh and cheese that has melted and browned in spots. The peppers should be easy to pierce, while their halves still hold the beef filling. Especially large poblanos may need a little extra oven time.

Why should the ground beef be broken into small crumbles?

Small crumbles brown more evenly and are easier to combine with the onion, seasonings, and tomato sauce. They also make the filling simpler to spoon into the pepper halves, helping it sit evenly rather than forming a few dense clumps.

What does the tomato sauce do in the filling?

Tomato sauce coats the cooked beef and brings moisture to the seasoned mixture. Stir it through so the chili powder, cumin, garlic, salt, and pepper are distributed, while keeping the filling cohesive enough to stay in the peppers.
