Tips
Prep all vegetables before cooking begins to streamline the skillet work and ensure even cooking times.
Break beef into tiny pieces while browning to distribute flavor throughout and create textural contrast.
Reheat potatoes gently before serving if they cool; the arrowroot or cornstarch slurry optional for those preferring thicker sauce.
Good to Know
Refrigerate in airtight container up to three days. Reheat gently on stovetop with splash of broth to prevent drying.
Chop all vegetables the night before and store in separate containers. Cook quinoa and potatoes up to two days ahead, refrigerate separately.
Serve warm, with additional fresh parsley and lime wedge on the side. Pairs well with a simple green salad or steamed broccoli.
Common Mistakes
Overscook potatoes to mush to avoid mushy texture that will not hold shape when plated.
Skip cold water rinse after boiling potatoes to prevent them from finishing cooking and becoming mushy.
Crowd the skillet with all ingredients at once to ensure even browning and proper cooking progression.
Substitutions
FAQ
Can I make this vegetarian?
Yes, substitute ground beef with crumbled firm tofu, tempeh, or legume-based ground meat and use vegetable broth instead of beef broth for a fully plant-based version.
How long will leftovers keep?
Stored in an airtight container in the refrigerator, this dish keeps three days. Reheat on the stovetop with a splash of broth to restore moisture and prevent drying.
Can I freeze the conquistador mixture?
Yes, the beef and vegetable mixture freezes well for up to two months. Thaw overnight in the refrigerator and reheat gently. Freeze potatoes separately for best texture.
