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
